Tahoe's sandhill cranes show wetland restoration is working
The region spent $3 billion in four decades on its environment. Sandhill cranes returned after a 100-year absence.
Dear Readers, I’m reposting this story from last year when I had maybe 40 followers. I was once lucky enough to call Lake Tahoe home, and my heart is always there. This spring, I was able to sit in the peace and quiet of Grass Lake—an ancient sphagnum bog created by glaciers—with six of these astoundingly graceful birds. The return of sandhill cranes after 100 years fills me with hope and awe for the power of ecosystem recovery. Thanks for reading. 🙏🏼
Sandhill cranes have discovered Lake Tahoe’s restored meadows, with four pairs breeding at South Shore, including a marsh that was rehabilitated as recently as 2023. This follows four decades1 of immense effort to stop development and cattle grazing, rebuild roads to prevent erosion, and actively revive all remaining wetland in the Tahoe Basin.2
Since 2000, the American people have spent nearly $3 billion restoring Lake Tahoe’s environment after it was logged, grazed, dredged, paved and developed to near death. Much of this restoration has been designed to encourage Tahoe’s meadows to get wet, stay wet, and act as the super filtration sponges and ecosystem boosters nature intended them to be.
Now, it appears those efforts are bearing fruit with the arrival of an absolutely stunning bird, one listed as threatened in the State of California. Only about 300 pairs nest in the bogs and marshes of northeastern California.
Will Richardson with the Tahoe Institute for Natural Science worked hard to raise awareness of the cranes’ nests, but elsewhere, the reaction from Tahoe’s environmental camp has been … crickets. That camp is too focused on clarity as gauge of progress.
Birders say cranes are multiplying in Tahoe because they’re “not hunted anymore” and “it was a wet winter.” These explanations are certainly valid, but they don’t capture the whole story. Hunting sandhill cranes has been illegal in California since 1918 and Tahoe has seen many wet winters since then.
Consider this: Commencing as early as the 1850s, Tahoe’s meadows were heavily grazed by cattle, sheep and horses. Beavers, our beloved wetland engineers, were already hunted to extinction3 in the region even before silver or gold miners arrived. Then, in the 1950s and ’60s, developers dredged, paved and infilled a majority of Tahoe’s wetlands.
This left meadows straining for life, streams suffocated or eroded down eight feet or more, and vegetation drying out. Rivers were straightened into ditches that funneled mud directly into the lake. Even in “wet years,” meadows would not flood. With no grass, willows and wildflowers, all the bugs, birds, amphibians and small burrowing animals lacked vital habitat. So, of course, big fauna like cranes weren’t sticking around to chase this nonexistent food.
Honey, that looks like a nice meadow down there
Tahoe began to turn the ship after 1980. The lake was losing the famed clarity John Muir and Mark Twain noted 100 years prior. Environmental groups, communities and land managers began a concerted effort to revive Tahoe’s ailing wetlands. Today, $3 billion and a few debates4 later, Tahoe boasts huge wetlands that sandhill cranes find very alluring.
We know that healthy meadows bloom with wildflowers that feed a multitude of insects, birds and small mammals. High-functioning meadows are sponges wet enough year-round for willows to thrive, creating great protective habitat for large birds. With plentiful willows to eat, beavers move in and help engineer more wetlands. Delicious crane food like frogs, voles and moles multiply, not to mention the fish nurseries that flooded meadows host with their small, braiding rivulets of sheltered, shallow channels.
Though they just started making news, cranes have been staging a quiet comeback for almost ten years, with a birder telling Tahoe In-Depth they’ve seen one in South Shore each year since 2015. In 2024, eight huge, 12-pound birds chose to raise chicks in four wetlands, a clear indication Tahoe is once again home to healthy, functioning and thriving ecosystems.
Which version of this meadow would you prefer?
Cookhouse Meadow is a 25-acre wetland just downstream of Grass Lake, where one of the pairs of cranes nested. It’s a perfect example of how meadows were degraded by grazing and poor road design and then later restored.5 Tahoe’s land agencies have conducted similar projects on over 1,100 acres of wetlands in the last 30 years.
A look at restoration work in or near the nesting sites
Two of the sandhill cranes’ 2024 nesting sites received significant restoration in the last 20 years, resulting in a transformation from dry to wet habitat:
Upper Truckee Marsh
Adjacent to the Tahoe Keys, the 560-acre Upper Truckee Marsh was dredged, dried and sacrificed to cattle until 2001. Since then, the California Tahoe Conservancy has placed enormous effort into resuscitating it, since this is the exit point for all sediment carried by the lake’s main tributary. When restoration began 20 years ago, it took 8,000 dump truck trips to remove the dirt the Tahoe Keys developers left behind in the ’60s. In 2023, the Conservancy completed an $11 million project to ensure the meadow floods and slows the flow of sediment into the lake, the largest restoration of this type in Tahoe’s history.
Washoe Meadows State Park
This 861-acre park was purchased by the State of California in the 1980s after a new regional plan halted a huge planned subdivision. The park contains a fen, a unique type of peat-forming wetland that takes thousands of years to form. Washoe Meadows received many upgrades in the 2000s that helped it transform from a dried out field to a lush meadow, including an updated sewer line, restoration of Angora Creek from straight to meandering, and a bridge through a flooded area so that pedestrians and bikes wouldn’t trample vegetation. More restoration is in store for this park, since Lake Tahoe’s largest tributary, the Upper Truckee River, passes through it.
The next two sites are usually quite wet and flood well during heavy snowmelt. Though altered by highways and pavement, they have not required as much restoration.
Pope Marsh
Pope Marsh (150 acres) sits on the other side of the Keys from the Upper Truckee Marsh and is surrounded by pavement on four sides, except one small length of lakefront sandbar. This includes a parking lot that provides beach access to some of Tahoe’s yearly throng of 15 million tourists. Since it’s so close to the lake, the marsh’s water level tracks pretty closely with lake level.6 The area is benefiting from $23 million in stormwater drain improvements along Highway 89 that encourage water to seep slowly into the ground, recharging wetlands instead of running along the road and causing erosion. Gardner Mountain Meadow, which would be contiguous with Pope Marsh if it weren’t for the highway running through it, received restoration work on 10 acres in 2014.Grass Lake
At 2,400 acres near the Lake Tahoe Basin’s southernmost tip, Grass Lake is the Sierra Nevada’s largest floating or “quaking” bog, making it the most unique of the cranes’ nesting sights. Except in winter, when it’s a cross-country ski destination, this giant floating matt of grass is difficult for people or predators to traverse, which could be why there’s little sign of historic cattle grazing. If I were a crane, I’d feel somewhat safer from the coyotes, bears and human pets here.The bog runs adjacent to Highway 89 for several miles, which in 2010 received new stormwater drains for $26 million between Meyers and Hope Valley. The drains prevent a gully of mud from running downhill alongside the highway. These road improvements ideally allow more snowmelt to seep into the bog, especially from the north, where previously the highway would have blocked and diverted some flow. Sandhill cranes were first spotted nesting at Grass Lake in 2018.7 8
Nowadays, what the cranes see when they fly above South Shore is not one nice marsh, but several, spanning thousands of acres, creating an interconnected hunting ground and a vast buffet by which to feed their chicks.
Lake Tahoe is known for its sparkling clarity. An environmental movement arose in the 1950s to preserve that clarity, which can be enjoyed down to 100 feet in some areas. Clarity measurements have been a single gauge of progress. But now we have another indicator that things are working.
These iconic cranes are an irrefutable sign that we are saving Lake Tahoe. We can do the same with rivers, lakes, and wetlands around the world.
There’s much more work to do. But this is a true success story. Tahoe should be proud.
“As it lay there with the shadows of the mountains brilliantly photographed upon its still surface, I thought it must surely be the fairest picture the whole earth affords.”
— Mark Twain on Lake Tahoe
“Tahoe is surely not one but many. As I curve around its heads and bays and look far out on its level sky fairly tinted and fading in pensive air, I am reminded of all the mountain lakes I ever knew, as if this were a kind of water heaven to which they all had come.”
— John Muir

A brief timeline:
The Porter Cologne Act of 1969 (California’s precursor to the nationwide Clean Water Act) prohibits dumping raw sewage into the lake.
1987: Tahoe Regional Plan prohibits development in any wetland within the Tahoe Basin.
1997: Tahoe Environmental Improvement Program (EIP) launches to secure public funding to improve stream restoration and stormwater runoff infrastructure, among other goals.
1999: Forest Service bans cattle grazing in Big Meadow Creek and Upper Truckee River watershed due to bacterial contamination and pressure from Lahontan Region Water Quality Control Board.
2000: Original Lake Tahoe Restoration Act passes Congress, provides money for wetland restoration.
2002: Forest Service bans cattle grazing in 12,000-acre Meiss Meadows, the southernmost reach of the Tahoe Basin watershed.
2012: Tahoe’s current regional plan encourages removing development from meadows. Developers can buy and restore parcels in meadows in exchange for development rights elsewhere.
2024: Nearly 1,100 acres of meadow and stream habitat have been restored as part of the EIP.
2024: We’re not done! California Tahoe Conservancy buys 31-acre site that includes Motel 6, which was built on a meadow with eight feet of infill. The purchase allows the Conservancy to remove the motel and connect the the Upper Truckee Marsh (crane nesting site number one above) with another several hundred acres of floodplain south of the highway. I’m hoping the future for Highway 50 here is a raised bypass similar to what Maui installed to traverse its Keālia Pond National Wildlife Refuge.
The “Lake Tahoe Basin” is a watershed as well as a jurisdiction. It covers the 500 square miles of tributaries draining into Lake Tahoe. In addition, a unique bi-state regulatory system, the Tahoe Regional Planning Compact, was created by California and Nevada and ratified by Congress in 1969 and again in 1980 to oversee the watershed, regulate development and restore the lake. The Tahoe Basin stretches across two states, five counties and one incorporated city.

An understatement
“Cookhouse Meadow gets a face lift,” by Amanda Fehd (yes, that’s me😊)
The top six feet of Lake Tahoe is a reservoir, with a small dam in Tahoe City run by the Bureau of Reclamation. The lake’s maximum elevation is 6,229 feet. During drought years, the lake can fall below the level of the dam.
Notably, 2018 was an average winter, but it followed the heavy winter of 2017. Likewise, 2024 was a slightly above-average winter, but followed the off-the-charts winter of 2023, when Tahoe received four feet of snow ten weeks in a row.

Thank you, Amanda, for that inspiring post and the accompanying photos! What a gorgeous bird that crane ie‼️
What a wonderful day to be alive! This is a great news, a true model to imitate around the world to save our crumbling ecosystems. 💜
