Improving Aquatic Habitat and the Distribution of COlorado River Cutthroat Trout and Other Important Native Fish Species
Numerous rivers and streams in the WLCI area support sensitive fish populations. The primary conservation objectives being addressed by LPDTs is to ensure sensitive fish species have access to as much suitable habitat as possible for seasonal and reproductive needs. This is primarily being accomplished through the removal of pilings, removing or replacing diversion structures, reducing bank erosion, increasing the number and quality of pools, balancing pool to riffle ratios, and reducing the temperature of water at select locations. Other activities are directed at increasing juvenile fish habitat, preventing hybridization between sucker species, and increasing water quantity and fish use in transitional areas (between cool water and warm water fish zones). LPDTs have prioritized fish species identified by WLCI partners as species of greatest conservation need. These include bluehead sucker (Catostomus discobolus), flannelmouth sucker (Catostomus latipinnis), roundtail chub (Gila robusta), Colorado River cutthroat trout (Oncorhynchus clarkii pleuriticus), Bonneville cutthroat trout (Oncorhynchus clarkii utah), and northern leatherside chub (Snyderichthys copei). 
 
Treatment approaches and treatment areas largely address WGFD Basin Management Plans and issues and needs identified for Aquatic Priority Areas. Project locations have been identified by the BLM, USFS, County Conservation Districts, Trout Unlimited, and USFWS Partners Program. Proposed treatment objectives include: removing barriers and impediments to fish movement; creating or maintaining fish barriers where beneficial to specific species, protecting genetics; developing rock sills to improve hydrologic function and increase water flow to side channels; increasing fish population numbers and maintaining their diversity; removing or treating unwanted invasive fish species; reducing impacts from sedimentation resulting from erosion; reducing salinity and environmental contamination; and increasing the resilience of aquatic habitats to buffer against prolonged droughts and climate change.
