This project is an ongoing cooperative project to restore 6,300 feet of Battle Creek and replace two irrigation structures which currently block seasonal fish migration. This joint project will improve native Colorado Cutthroat fish habitat, improve thermal and low flow habitat, and reduce bank erosion. Restoration will include narrowing the channel to accommodate for 590 cfs bankfull flows; excavating pools and installing fish-hook vane structures to improve low flow trout habitat; and re-establishing riparian vegetation to prevent further erosion. At a minimum, the project will include the following: installing 10 fish-hook vanes, excavating 12 pools, installing bank full benches to narrow the channel, installing...
This is an ongoing cooperative project to restore 6,100 ft of Savery creek. This joint project will improve native Colorado Cutthroat fish habitat, improve thermal and low flow habitat, and reduce bank erosion by approximately 1,000 cubic yards per year. Restoration will include narrowing the channel to accommodate for 220 cfs flows; excavating pools and installing fish-hook vane structures to improve low flow trout habitat; and re-establishing riparian vegetation to prevent further erosion. At a minimum, the project will include the following: moving three mid-channel bars, installing 14 fish-hook vanes, excavating 18 pools, installing 27 bank full benches to narrow the channel, installing 226 willow clumps...
There is a critical need to increase the level of control to minimize the economic and ecological impacts that invasive species cause. BLM has a commitment to Sweetwater County and private adjacent land owners for controlling weeds. Control of noxious weeds is a priority within the local county and the Bureau. Native wildlife species, including elk, mule deer, greater sage-grouse, mountain plovers, raptors, Colorado River cutthroat trout and many juniper obligates, are dependent on native vegetation for successful breeding, nesting, and food. Protection of their habitats is of primary importance. One community at risk is riparian habitat where invasive weeds are displacing native species. Weeds affect streams by...
Populations of Colorado River cutthroat trout (CRCT) have experienced dramatic declines throughout their historic range. Current distributions of CRCT are typically limited to isolated headwater streams and lakes. Primary threat to the CRCT is the introduction of non-native salmonids and loss of habitat. A fish barrier on Dirtyman Creek was placed on BLM administered lands to prevent invasion of non-native salmonids and maintain a genetically pure population of Colorado River cutthroat trout. However, the existing structure has degraded over time and needs to be replaced before the integrity of the barrier is lost. The goal of this project is to prevent non-native fish from invading upstream of the existing barrier...
This map shows the potential current distribution of Colorado River Cutthroat Trout as well as current and near-term status, and long term potential for change (due to climate change).

The Colorado River Cutthroat historically occupied most cool water habitats of the Colorado River watersheds in Colorado, southern Wyoming, eastern Utah, extreme northwestern New Mexico and northeastern Arizona. Currently, however, Colorado River Cutthroat trout occupy approximately 16 percent of its historic range, primarily in isolated, small headwater streams. About eight to nine percent of the occupied historic range is classified as "Conservation Populations." The Colorado River Cutthroat has been called one of the most spectacular of the cutthroat trout and one of the most beautiful fish in North America.
