Lahontan cutthroat trout occupy less than 9 percent of their historic stream and river habitat according to Trout Unlimited's State of the Trout Report.
Working to protect and restore the headwaters of North American streams and rivers benefits more than trout.
A myriad of species rely on the environments in and around the top reaches of rivers across the country. Most of the animals are native to the American landscape, but some were introduced and have played a key role in the livelihood of families for more than a century. Ranchers in the West have realized throughout the years that waters capable of supporting trout are also good for their cattle and the surrounding landscape.
A watershed restoration project on private and public land near Elko, Nevada, is benefitting threatened Lahontan cutthroat and the cattle of the Heguy family. The Susie Creek project has been highlighted by the Nevada Cattlemen's Association and the Elko District of the Bureau of Land Management in the first of a series of articles showcasing ranching conservation projects on Lahontan cutthroat trout streams in Nevada.
The first piece recently ran in the Elko Daily Free Press and included this introduction from the authors. The stories will also run in various cattle industry publications.
Carol Evans, a BLM fishery biologist, co-wrote the piece with Torell.
Trout Unlimited participated in the Susie Creek project to evaluate habitat recovery. The TU science team used satellite imagery and aerial photos three decades old to track the progress.
Susie Creek as seen during a BLM Stream Survey in October of 1978. Stream and riparian habitat conditions are poor as shown by a poorly defined channel and a drying floodplain. Most of the riparian vegetation on the floodplain is comprised of Kentucky bluegrass and other shallow-rooted species typical of a lack of persistent soil moisture.

Susie Creek as seen from a BLM Stream Survey in May of 2015. Since implementation of rotational grazing practices in this area starting in 2008, Susie Creek is narrower and deeper and streambanks are stable and well vegetated. The floodplain is much wetter now and supports wetland plant species over a broad area. Note the area of new floodplain developing between the stream channel and the terrace slope to the right.

The Heguy family allotment includes 37,000 acres of public land and 13,000 acres of private. Restoration work was done on the entire allotment and included help reseeding native vegetation from the U.S. Fish and Wildlife Service after a wildfire, water developments to draw cattle away from riparian areas and a pasture to manage timing and duration of grazing on the land.
The benefit for the threatened trout is colder water and more of it, as well as critical streamside vegetation. The evaluation showed riparian vegetation in the entire Susie Creek Basin increased by more than 100 acres. There had been no beaver dams in the system and there were 139 when the evaluation was done. More water was visible on the landscape and well monitoring showed an increase in shallow aquifers.

After seven years of rotational grazing management, the spring complex is saturated at the surface and wetland plant species such as sedges and rushes are expanding into adjacent uplands.
