In no particular order, here’s a snapshot of 10 of our biggest river wins of 2025: 

1. Secured major wins for America’s Most Endangered Rivers® of 2025 

Our 2025 America’s Most Endangered Rivers® report ranked the Tijuana River #2 due to toxic pollution threatening border communities. This designation, developed with partners Surfrider Foundation and Un Mar de Colores, helped catalyze swift federal action. Within three months of the April report release, American Rivers and others were invited to meet with EPA Administrator Lee Zeldin in southern California, which helped build momentum for a landmark agreement between the United States and Mexico to address the ongoing public health crisis. This demonstrates how strategic advocacy, combined with persistent community leadership, drives solutions for rivers and their communities. 

The Rappahannock River’s designation as one of America’s Most Endangered Rivers® of 2025 brought crucial national attention to the threats facing Virginia’s longest free-flowing river. But this spotlight did more than raise awareness; it galvanized action that delivered tangible results. Working alongside our dedicated partners, The Friends of the Rappahannock, the Rappahannock Tribe, and the Southern Environmental Law Center, we achieved a significant victory for the river and the communities that depend on it. This collaborative effort secured permit changes for a proposed data center, banning industrial cooling withdrawals and reducing drought withdrawals by millions of gallons.

2. Mobilized action to protect Public Lands and Roadless Areas 

Bipartisan public outcry over a disastrous sell-off provision in a massive tax and spending bill led to the protection of public lands and the rivers that flow through them. Victory was snatched from the jaws of defeat thanks to supporters like you. 

The Trump administration is looking to rescind the Roadless Rule, which protects clean water and wildlife habitat by preventing road construction and timber harvest on roughly 45 million acres of national forests. This would be a significant setback (100,000 river miles) to our goal of protecting one million miles of rivers. Our team is making sure decision makers understand the impacts to clean drinking water supplies and we are mobilizing our supporters (we’ve collected more than 10,000 signatures so far) in support of these important river protections.

3. Safeguarding Montana’s Gallatin and Madison Rivers 

Rep. Ryan Zinke (MT) introduced the Greater Yellowstone Recreation Enhancement and Tourism Act (GYREAT Act) – Wild and Scenic legislation to protect nearly 100 miles of the Gallatin and Madison rivers and their tributaries in southwestern Montana. This legislation was developed through collaboration with American Rivers and our partners. If passed, these protections would create a vital corridor linking the rivers of Yellowstone National Park to the headwaters of the Missouri River.

4. Defending healthy rivers and Tribal sovereignty 

American Rivers helped rally national, regional, and local partners in urging the Department of Transportation to protect aquatic connectivity programs — efforts that restore fish passage, reconnect rivers and wetlands, and replace outdated culverts and road crossings. The joint comment letter was signed by 140 groups — including Tribes, anglers, businesses, universities, research institutions, conservation organizations, community leaders, agencies, faith groups, and planners — all united for healthier, more connected waterways. 

Additionally, when the Department of Energy urged the Federal Energy Regulatory Commission to roll back its 2024 policy protecting Tribal sovereignty in hydropower permitting, American Rivers acted fast. Working with Tribal attorneys, Native networks, and partner organizations, we mobilized national opposition and filed formal comments — demonstrating our deep commitment to Tribal leadership and ensuring healthy rivers. We’ll continue working alongside Tribal partners to ensure these protections remain strong.

5. Restoring mountain meadows in California 

American Rivers is a key member of The Sierra Meadows Partnership, a coalition of environmental organizations working together to restore 30,000 acres of mountain meadows by 2030. These meadows act as natural sponges that store water, improve drought resilience, and provide essential wildlife habitat. Through this collaborative effort, we successfully secured a $24.7 million block grant from the Wildlife Conservation Board to support our restoration work.

6. Advanced critical protections for New Mexico’s waterways 

After naming New Mexico’s waterways #1 on America’s Most Endangered Rivers® of 2024 list, we’re celebrating significant wins across the state. In the Pecos watershed — home to elk, black bears, Rio Grande cutthroat trout, and generations-old acequia farms — the Department of Interior paused new mining claims across 165,000 acres while pursuing longer-term protections. Through advocacy with our partners, we helped secure Outstanding National Resource Waters protection for over 250 miles of rivers across five watersheds, including the Rio Grande. And now, Senator Heinrich (NM) and the All Pueblo Council of Governors are championing protection of the Caja del Rio — a 107,000-acre landscape along the Rio Grande and Santa Fe rivers that holds deep cultural significance for Puebloan and Hispanic communities while supporting diverse wildlife.

7. Furthering community safety through dam awareness 

American Rivers spoke on panels and hosted webinars addressing the deadly threat of low head dams, generating hundreds of participants from across the dam removal and safety industries. A low head dam is a human-made structure that spans the full width of a river and is designed to allow water to continuously flow over it, creating a dangerous hydraulic and earning them the nickname “drowning machines.” Our educational workshops brought together leading experts to discuss solutions for addressing these public safety hazards while advancing river restoration solutions.

8. Building momentum for dam removal across the Northeast 

American Rivers is celebrating a wave of funding that will free multiple rivers across the Northeast. We were awarded $220,000 to remove the Yopp Pond dam on the Fourmile River in Connecticut — the first barrier blocking this coastal river that drains to Long Island Sound. Fisheries biologists note this removal will be transformational for alewife runs in this critical watershed. Additionally, New Hampshire Fish and Game committed $150,000 to support two strategic dam removals: North Branch Gale dam in the Upper Connecticut River watershed and Mead Brook dam in the Contoocook River watershed. Both dams impact excellent cold-water habitat and are scheduled for removal in 2026. Additionally, the Davis Conservation Foundation granted $20,000 for our hydropower relicensing work in Maine.

9. Defended Idaho’s Salmon River 

Along with our partners at Advocates for the West and coalition members in Idaho, American Rivers and our Action Fund filed a lawsuit against the Forest Service to prevent a massive open-pit gold mine at the headwaters of the South Fork Salmon River. This important waterway is a national treasure that provides critical spawning habitat for the longest-distance, high-elevation salmon migration on Earth, as well as world-class whitewater recreation and fishing. It has been listed as one of America’s Most Endangered Rivers® for three consecutive years.

10.  Improved wildfire resilience in California 

American Rivers and our partner, Terra Fuego Resources Foundation, completed prescribed fire burns on 160 acres as part of a 570-acre fuel reduction and prescribed fire project — a critical effort to protect the South Yuba River and the communities of Nevada City and Grass Valley from catastrophic wildfire. In a major boost for river restoration, the California Wildlife Conservation Board approved nearly $5 million to launch the Pickel Meadow Restoration Project on the West Walker River. Construction begins this summer, marking an exciting next chapter for this important watershed.

This year’s progress is thanks to you and thousands of passionate advocates, partners, volunteers, and expert staff who contribute to our mission daily. Together, we’re building a future of healthy rivers and clean water for everyone, everywhere.

The post 10 Big Wins for Rivers in 2025 appeared first on .

Currently, when the plant is running full steam, 1,400 cubic feet/ second (think 1,400 basketballs full of water passing by every second) is diverted out of the river into a tunnel and then into massive pipes visible against the canyon walls, where the power of falling water spins turbines to generate electricity. The water is then returned back to the river. Under the new deal, when the plant stops operating (it is over 100 years old and vulnerable to rockfall), the water would instead stay in the river, vastly improving conditions for fish and the bugs they eat in the 2.4-mile reach between the diversion and the powerplant’s return flows. The dedication of the plant’s water rights to that stretch of river would bring benefits that ripple hundreds of miles up and downstream because of the crucial role these water rights play in controlling the river’s flow through Western Colorado.  

In Colorado, as in most of the West, older water rights take priority over newer ones when there’s not enough water to satisfy everyone’s claims.  On the Colorado River, the Shoshone Hydropower rights limit the amount of water that can be taken out of the river upstream by junior rights that divert water from the river’s headwaters through tunnels under the Continental Divide to cities and farms on the eastern side of the Rocky Mountains. The new deal to enable the Shoshone rights to be used for environmental flows would preserve those limitations on transmountain diversions in perpetuity.  

Upstream from the power plant, near the ranching town of Kremmling, Colorado, the river carries less than half the water it would without the existing transmountain diversions. This stresses fish populations and the iconic cottonwood groves that line the river. The Shoshone rights downstream prevent these diversions from being even larger. Because the power plant returns all the water it uses to the river without consuming it, the water continues to provide benefits downstream from the plant to rafters, farms, cities and four species of endangered fish that exist only in the Colorado River Basin. Securing these flows for the future is particularly important as climate change continues to reduce the river’s flow, which has already declined by roughly 20% over the past two decades.  

The people cheering in the hearing room represented cities, towns, counties and irrigation districts from up and down the Colorado River. Their entities had pledged ratepayer and taxpayer dollars to help secure the rights in the complex transaction spearheaded by the Colorado River Water Conservation District. Environmental organizations, including American Rivers, Audubon, Trout Unlimited and Western Resource Advocates, were also parties to the hearing and supportive of the deal, but were vastly outnumbered.  

The Coloradans cheering in that room were there because their constituents’ livelihoods, clean drinking water and quality of life depend on a living Colorado River. American Rivers is proud to stand with them and will continue advocating for the completion of this historic water transaction.

A historic floodplain 

When the Yachicumne Yokuts and Miwok Tribes were the primary stewards of this portion of California’s Central Valley, the area had been freshwater wetlands that were naturally designed to flood. When settlers arrived in the mid-1800s, the wetlands were rapidly replaced with agricultural fields, and the river was hemmed in by levees built to protect farms and crops from flooding. Over time, Stockton grew into an urban and diverse community of more than 320,000 people.   

Although they remain the main tool to contain floodwaters, levees in the Central Valley are aging and in need of repairs. If the network of levees remains in its current state, it poses a great flood risk because the levees stand to fail as extreme precipitation threatens the region.  

This is an equity issue. The primarily working-class communities of color living near the levees lack the financial resources, like flood insurance, to recover from the hazards of living in a historic floodplain.  

As climate change increases extreme precipitation events and flooding, 1-in-5 San Joaquin River Delta residents will experience flooding each year, costing the city more than $28 billion in damages and impacting more than 17,000 homes by 2050, according to a study by the state of California. Finding a solution to address this risk is critical. 

Solution: Build a park and return floodplains to their natural state 

The historic wetlands native to the Central Valley were nature’s solution to flooding as the flat lands naturally disbursed excess water whenever the San Joaquin River was inundated. 

Levees that set the river in place didn’t allow it to breathe and flood like it naturally would. American Rivers is working with the city of Stockton, the U.S. Army Corps of Engineers, and community partners to address the aging levees and subsequent flood risk. Through the Van Buskirk Park Revitalization project, the city is working to provide recreational areas, while the Army Corps is leading the effort to enhance the levee system along the San Joaquin River.  

These projects have the unique opportunity to reconnect the river to historic wetlands and reduce flood risk, while providing more access to green recreational spaces, and potentially restore the area to a biodiverse habitat for wildlife. 

The difficult part is the planning. The city has been working since 2021 to plan the park revitalization efforts while coordinating with the Army Corps, community partners, and project partners to plan the levee project at Van Buskirk Park. Meanwhile, the Army Corps is also working to create room for low-impact recreation into the potential setback levee area, as required by the city, as well as the Van Buskirk family, when the land was given to the city.  

What to do with the levees? 

A big question is whether the Army Corps will repair and enhance the full levee where it currently stands or move a portion of the levee at Van Buskirk Park back from the river to create mitigation space that can give the river room to flood.  

Setting back levees produces an environment for fish, birds, and endangered species, while reducing flood risk to the community. 

The city of Stockton approved a master plan for the park revitalization project in 2023, which is when American Rivers joined to facilitate communication between different stakeholders and partake in planning the levee project. Since then, progress has been made to fund and permit the first phase of the park revitalization. The Army Corps is planning to enhance some stretches of the levee along Van Buskirk Park, but it won’t make a final determination on setting back a portion of the levee until 2029. 

Until then, construction for phase one of the city’s revitalization efforts is expected to begin in 2026, and that will include improving and building public amenities, including a community garden, bicycle pump track, splash pad, and other recreational spaces. The public should begin to see the immediate benefits of having more access to outdoor spaces. Although the decision to set back a portion of the levee is still in the air, there is incredible potential for an ecologically diverse, natural floodplain that will better protect the city from catastrophic floods. 

A model for flood-prone communities  

Both the Lower San Joaquin River Project and the Van Buskirk Revitalization Project complement each other to provide a model for other communities looking for green spaces and flood protection. For the revitalization effort, the city of Stockton completed several community meetings and surveys that led to the Van Buskirk Master Plan and the upcoming construction of Phase 1. As the project and funding progress, the city plans to hold even more meetings to ensure that the master plan holds true to the needs of the community. Upon completion, not only will people have renewed access to the park, but their involvement in park planning will also boost further engagement. Meanwhile, the US Army Corps of Engineers has the potential to create a setback levee that provides space for the San Joaquin River’s natural processes, while strengthening flood protection. These are exactly the kinds of innovative approaches we need if we want to work with our rivers rather than against them.

Thank you to all project partners, including the City of Stockton, US Army Corps of Engineers, San Joaquin Flood Area Control Agency, Department of Water Resources, Restore the Delta, and Trust for Public Land.

Scientists from the U.S. Forest Service have developed a system to identify potential “lost meadows.” The lost meadow model is based on the idea that disturbances like overgrazing, logging, and mining can disrupt the stability of a meadow, leading to big changes in their physical structure and biologic communities. One of the most troubling changes is the encroachment of large trees onto the former meadow surface. These trees use up water that was formerly available for wetland plants, and they increase fuels in forests that are already at high risk of catastrophic wildfire. 

Degradation like what is pictured above can render historic wetlands unrecognizable to a typical observer, but the lost meadow model uses satellite and hydrological data to narrow down the search. With these tools, thousands of acres of potential lost meadows were identified across the Sierra Nevada. 

This summer, American Rivers began a multi-year effort alongside the South Yuba River Citizen’s League and the U.S. Forest Service to find out how many of these lost meadows there really are in the North Yuba watershed in northern California, whose headwaters are almost entirely contained within the Tahoe National Forest. Field technicians like me spent months bushwacking through the Tahoe National Forest searching for these potential meadow sites by monitoring their vegetation, hydrology, and geology to determine if they were indeed historic wetlands and if they could be restored. 

One season in, the results are surprising: after assessing more than 1500 acres of potential lost meadow sites, a vast majority were accurately predicted by the model (many were even bigger than projected!). We won’t have all the numbers until the project is complete, but the implications of our results so far are significant. If there are even half as many lost meadows in the Sierra Nevada as the model predicts, the restoration of these wetlands could substantially increase the water storage capacity of the Sierra Nevada, bring back historic habitat for wetland species, and sequester more carbon than is currently possible in their degraded state. 

The benefits offered by the restoration of lost meadows in this region don’t stop there, though. As catastrophic wildfire risk continues to grow nationwide, it is clearer than ever that responsible forest and watershed management is crucial to protecting rivers, wildlife, and people. Strategic lost meadow restoration could lead to significant forest fuel reduction in a region that desperately needs it. Meadow restorations that remove unhealthy growth, create natural fire breaks, and increase surface water during the driest seasons become ever more important, and understanding lost meadows could be key to accelerating fire-safe restoration across the Sierra Nevada and beyond.  

These findings open an exciting new chapter in meadow restoration. At the conclusion of this watershed-scale assessment, we’ll be able to begin exploring entirely new restoration techniques at meadow sites we didn’t know existed, working in collaboration to unlock all the benefits these ecosystems can provide.

As the river moves through the modified channel, it carves deeper into the valley floor and less frequently spills over its bank. As a result, the local water table has dropped, and riverside trees such as cottonwoods have died, impoverishing this important habitat. Water users on the Ward Ditch at the top of the valley were also struggling with broken-down infrastructure, making it difficult to access and manage water for irrigation. This confluence of challenges created a landscape of opportunity for the Uncompahgre Multi-Benefit Project, which addresses environmental problems along the river and water users’ needs, while also improving water quality and reducing flood risks downstream. 

The Project, managed by American Rivers, took an integrated approach to restoring a one-mile stretch of the river, which included replacing and stabilizing the Ward Ditch diversion, notching a historic berm to reconnect the river to its floodplain, and placing rock structures in the river that both protect against bank erosion and improve fish habitat. Meanwhile, ditch and field improvements make it easier to spread water across the land for agriculture and re-establish native vegetation.

In addition to the direct benefits this project delivers for on-site habitat and landowners, the enhanced ability of the river to spread out on its floodplain, both through the ditch diversion and natural processes, also provides downstream benefits. As the water slows and spreads across the floodplain during high flows, its destructive power to erode banks and damage infrastructure downstream is diminished. The same dynamics enable pollutants and sediment from upstream abandoned mines or potential wildfires to settle out before the river flows into the downstream reservoir.

With construction wrapping up in November 2025, the transformation of this stretch of river and its adjacent floodplain is nearly complete.  Fields of flowers and fresh willow plantings are replacing invasive species and dead cottonwoods, and new pools, sandbars, and riffles are providing instream habitat, complementing other organizations’ work to remediate old mines upstream. As a bonus, when the water level is right, the reach has become an inviting run for skilled whitewater boaters.

The Uncompahgre River Project would not have been possible without the close collaboration of local landowners, the Uncompahgre Watershed Partnership, the support of the Ouray County Board of County Commissioners, and generous grants from the US Bureau of Reclamation, the Colorado Water Conservation Board, and Colorado River District.  American Rivers and our partners are hopeful that this project will inspire other water users downstream to undertake similar projects to keep the momentum going and bring renewed vitality to the entire upper Uncompahgre River and surrounding agricultural lands.

We lost valued community members.

We lost access to natural spaces we relied on for recharge and connection.

The rivers we loved for fishing, paddling, and sustaining local businesses were left clogged with trash and debris.

Infrastructure like roads, bridges, and dams failed — leaving disconnection and communities at risk.

When I think back to those early days, I remember hearing the same question again and again: “Where can I help?” And the answer was simple, help your neighbors. We formed flush brigades (without running water we hauled non-potable water for flushing toilets), filled each other’s drinking water jugs, and shared hot drinks in my driveway as we organized to make sure that everyone had what they needed most.

Of course, restoring rivers is also my job. In order to be most helpful, I knew we needed to work together with local partners — who in many cases were my neighbors. With MountainTrue and Riverlink we listed the Rivers of Southern Appalachia on America’s Most Endangered Rivers® list to call for the resources we need to recover. Our advocacy centered on making rivers and communities safer — by addressing high-risk dams, removing storm debris, rebuilding stronger water infrastructure, supporting voluntary floodplain buyouts, and ensuring access to federal recovery funds.

The progress of the past year has been grounded in one clear goal: not just to repair rivers, but to make them more resilient for the future. One major win came through House Bill 1012 that created the new North Carolina Dam Safety Grant Fund with $10 million dedicated to addressing high-hazard dams damaged by Helene. Additional resources flowed to MountainTrue to support storm debris cleanup which created jobs and ensured ongoing reciprocity for our rivers. Another silver lining was when we brought the community together to celebrate at New Belgium Brewing to toast our hard work and take action for the work that’s ahead.

Recovery doesn’t end when the debris is cleared or when the funding comes through for the dam removal. True resilience means preparing for the future knowing that the next storm is on the horizon, focusing on advocacy efforts that will help long term.

 America’s Most Endangered Rivers® calls on communities to spotlight the rivers at a crossroads, where decisions in the next year will shape their future for decades. Nominations are open now and it is a powerful way to keep community safety at the forefront of public attention.

As I mark this anniversary, I feel deep gratitude for the rivers that keep flowing, for the partners who stood shoulder to shoulder in recovery, and for the colleagues who continued to inspire me with their commitment and care. Helene reminded me that resilience is both a collective and personal journey. As we look ahead, I carry the resolve that we can and must build a future where rivers — and the people who depend on them — are ready not just to survive the next storm but to thrive in its aftermath.

When the federal government recently withdrew from a historic partnership known as the Resilient Columbia Basin Agreement, we knew it was time to take to the river once again to chart our path forward. We helped the Nez Perce Tribe lead a team of 17 Tribal representatives and multiple state legislators, congressional staff, and non-profit partners on a five-day Snake River trip through Hells Canyon, on the border of Oregon and Idaho. During this impactful trip, the group discussed current challenges and the historical context that brought us to this point, and brainstormed solutions for our region’s future. 

Convening in Idaho: Day 1 

After everyone arrived in Lewiston, we met up with EcoFlight to get an aerial view of the river and the surrounding landscape. We flew over the confluence of the Snake and Clearwater Rivers, through golden dryland wheat fields as far as the eye can see, and over Lower Granite Dam, where we spotted a lone wood products barge waiting at the lock for passage downriver. 

Our group then joined the festivities at Hells Gate State Park, where groups were preparing food, art, and music for a “Free the Snake” flotilla the following day.  

Not long after arrival, we all went to bed to get ready for our early flight to meet our river guides in Halfway, Oregon, for our descent through the deepest gorge in North America. 

On the river: Day 2 

After a safety talk the next morning, our giddy group began our four-day, three-night journey downstream. With the launch dock still in sight, we landed a rainbow trout on the first cast – clearly a good omen for the trip to come.  

Our first lunch stop offered a warm welcome to Nimiipuu country from our gracious Nez Perce hosts, where we were grounded in creation stories and the importance of salmon, who represent the “first treaty” of a sacred promise between the animals and the Creator to care for the Nimiipuu people.  

We took turns sharing who we were, where we came from, and our intentions for this experience.  

After an easy day on the water in bright blue paddle rafts and sporty inflatable kayaks, we spotted a round black bear on the hillside, right above our camp. While our guides prepared dinner, a lively game of UNO sent laughter into the canyon, and the first of several sturgeon fishing efforts got underway.  

After a bit of fun, it was time to get to work. We had an in-depth conversation about the Columbia River Basin, which included the health of the fish that depend on it and the results of our conservation efforts. We used clothing props and home-laminated maps to aid the conversation, which continued through dinner and dessert, until the darkened canyon told us it was time to go to sleep.  

On the river: Day 3 

Day 3 started with early morning conversations about regional energy needs over camp coffee. To advocate responsibly for breaching the four hydroelectric dams on the lower Snake River, we need to co-create clean energy alternatives that consider impacts to Tribes.  

Lunch was dedicated to learning about first foods and seasonal rounds. Tribal members generously shared their histories and ties to place, how important their traditional foods are to their culture and well-being, and how each Tribe and place are unique. 

After paddling through Wild Sheep and Lower Granite rapids, most of our crew beat the heat by jumping in the water to float the remaining distance to our second camp. Our group had found the river magic!  

Although this camp is technically called Oregon Hole, I will forever remember it as Sturgeon Hole. Since we were skunked the previous night, I wasn’t holding my breath that we would land a fish. A little later, while I was setting up my tent at the edge of the campground, I heard hoots and hollers and immediately knew what was happening – we got one! 

My good friend, Rein Attemann, had reeled in a six-foot sturgeon! The fish was in the water, upside down, while a Nez Perce biologist evaluated her and explained her physiology to the captive group.  

Like sharks, sturgeons are mostly made of cartilage, and flipping them upside down induces a trance-like state called “tonic immobility”. In this state, the fish becomes calm, allowing them to be handled gently before being released.  

After dinner, we heard the second sturgeon line ping and several of us raced down to the water. I was keen for this experience and had bought a fishing license in Halfway. It took me a few tries to develop a rhythm, and reeling in this fish was no easy task, but as she got closer to the boat, I could see she was beautiful, mysterious, and massive – like a living dinosaur.  

At 7.5 feet in length, she was likely at least 50 years old, making her bigger and older than me. She was probably alive before some (or all) of the four lower Snake River dams were constructed. She had a Floy tag, which meant she had been caught before. We wrote down the numbers to report to Idaho Fish and Game, turned her right side up, and released her to power downriver.  

On the river: Days 4 and 5 

Our last full day and a half on the river was filled with deeper conversations about how to develop a truly just energy transition in the Northwest, in partnership with Tribal Nations, and how to face opponents and stakeholders who resist the restoration of the Snake River and greater Columbia Basin.  

Our time was also punctuated by play and laughter – it’s important to have fun and take care of each other along the way.  

Being on the river brings out the most intense and authentic version of who people are. It allows relationships and conversations to progress at warp speed relative to what is possible in the normal course of our work. I returned home confident and knowing that this group can do hard things. We will keep up the momentum, keep supporting each other, and continue to have the hard conversations – preferably on the river!

The work at Ackerson is a gift that will keep on giving to generations of recreators, wildlife enthusiasts, and downstream water users. The benefits of restoring mountain meadows are both significant and wide-ranging, and a restored meadow has a sort of multiplier effect on the surrounding landscape and watershed. A healthy, fully restored Ackerson is projected to store 70.8 million gallons of groundwater each year, or enough water to satisfy the daily use of almost 250,000 households, while filtering out pollutants before flows enter the South Fork Tuolumne River. Of course, California is known as a global biodiversity hotspot, and Ackerson Meadow is home to nearly 60 species of birds and provides refuge for threatened and endangered species such as the Little Willow Flycatcher, Great Grey Owl, and northwestern pond turtle. 

But Ackerson is also a gift for scientists and agencies who want to see this sort of work fine-tuned and expanded. We will monitor the site over the coming years, and the findings will feed into this ‘meadow movement’ organized by the Sierra Meadows Partnership, as we quantify the benefits of restoration: hydrological changes, soil carbon sequestration, and habitat recovery for endangered species.

Outside of the direct benefits to rivers, ecosystems, and the scientific community, Ackerson is both a milestone and a launching pad, setting the table for expanded public-private partnerships with the federal land management agencies and nonprofit conservation organizations. Through our years of project management, we demonstrated how a nonprofit like American Rivers can bring technical expertise, fundraising capacity, and the flexibility to achieve conservation outcomes in short order.  These partnerships and this project have shown not only the power of collaboration across different sectors, but also how a common vision can be approached from different angles, leveraging our collective expertise to the benefit of the communities we live in, the wildlife we cherish, and the rivers that are the lifeblood of California.

In these 20 years, we have learned a lot about the challenges with levees and the importance of healthy, connected floodplains. Our Senior Director of Floodplain Restoration, Eileen Shader, reflects on these lessons and how state and federal governments can act to prevent that scale of destruction from happening again. 

What can you do to help? 

Take action: Tell states they must step up to make sure they are investing in floodplain management and floodplain reconnection and flood safety, and that that they have the rules and regulations in place to help guide local government and local decisions about where we develop and how we develop in floodplains to keep people and property safe.

But how did American Rivers identify Wilson Ranch as the next meadow restoration project? Our meadow restoration work follows a life cycle that starts with watershed-scale assessment and prioritization to identify impactful restoration opportunities, followed by planning, restoration, and adaptive management of the highest priority meadows. We started this process in the American River watershed in 2016 using the meadow condition scorecard, a rapid assessment tool. This tool was developed by American Rivers, University of California, Davis, and the U.S. Forest Service, to quickly gauge the health of a meadow. Using the scorecard data, a group led by American Rivers identified Wilson Ranch Meadow as a high priority for restoration which then kick-started design and permitting work in 2019, later culminating in a road crossing replacement and full-fill channel restoration in 2023 and 2024, with adaptive management slated for fall 2025.

This meadow in particular serves as a stopover for migratory bird species such as willow flycatcher and provides important habitat for species like the southern long-toed salamander. The restoration phase of the project was completed last September, making this spring and summer the first time we were able to see the impacts on the hydrology of the meadow. The photo below shows flows spreading across the meadow, whereas before they funneled into an incised channel and drained away from the meadow before it could provide support for native plant and animal species. The Wilson Ranch project is now in the adaptive management and post-restoration monitoring phase, where we will continue to measure the effects of restoration and ensure our impact on the ‘fireshed’ moving forward. In September of this year, we will complete adaptive management to prevent erosion and the incision the channel, and will also continue to monitor groundwater levels, vegetation, and soil carbon in the meadow.

Throughout the restoration life cycle of Wilson, California experienced some of its largest and most destructive wildfires in recorded history. It became apparent that the qualities that sustain a healthy meadow for clean water and wildlife, also make them excellent at mitigating the negative impacts of wildfire by capturing sediment and runoff and providing high quality habitat for all life that depends it. Healthy meadows can also serve as natural breaks in fuel that can help prevent the spread of wildfire. With this in mind, American Rivers pivoted from a watershed-scale approach to a ‘fireshed’ based approach for the first time. In coordination with our partners at the Eldorado National Forest at Wilson, we updated our prioritization process to incorporate factors such as burn severity and sediment capture potential and shifted our focus to the Caldor Fire footprint, which burned approximately 167,000 acres of Eldorado National Forest in 2021.

The Wilson Ranch project and our prioritization work in the Caldor Fire footprint speak to the collaborative approach we bring to restoration work, working alongside partners such as Eldorado National Forest and in coalitions such as the Sierra Meadows Partnership and the Healthy Eldorado Landscape Partnership that are larger than the sum of their parts. This is the driving philosophy behind the landscape-scale healing of California’s watersheds, and post-fire recovery and wildfire resilience in an era of a changing climate. And as we wrap up this prioritization process, we are looking forward to tackling new restoration projects that support wildfire recovery and resilience in the Caldor region.

The restoration at Wilson Ranch Meadow was funded by the California Department of Fish and Wildlife, the California Wildlife Conservation Board, and the National Fish and Wildlife Foundation, all of whom have been ardent supporters of meadows and the wildlife that depend on them for many years.
