  • WRI - Utah Division of Wildlife Resources
  • Bureau of Land Management

Important tributaries to the UCR have been impacted by hydrological alterations, habitat fragmentation, and non-native woody riparian vegetation establishment. In the lower river areas, spring snowmelt floods have declined in magnitude and duration due to water capture in the upper portion of the basin.
The overall objective and mission of this proposed restoration and monitoring project is to guide conservation and recovery efforts targeted to imperiled and endemic fish species and riparian corridors in desert tributaries of the upper Colorado River Basin. This project represents ongoing efforts initiated on the San Rafael in 2006 and is part of an effective partnership between the BLM, Utah State University, the Utah Division of Wildlife Resources (UDWR) and the Bureau of Reclamation (BoR). This partnership is dedicated to science-driven and innovative desert river restoration. Our project has direct benefits to natural resource management and invasive species prevention.
