Blue Creek Watershed Assessment & Restoration Prioritization Plan

Category
Watershed and Stream Assessments
Client / Agency
Lower Clark Fork River Watershed Group
Location
Clark Fork, Idaho/Heron, Montana
Date
2007 to 2008
Project Description
Blue Creek is tributary to the Lower Clark Fork River at the Montana-Idaho border and is comprised of the three sub-watersheds including West Fork Blue Creek, Wiggletail Creek and East Fork Blue Creek. Encompassing nearly 30 square miles, the Blue Creek watershed provides habitat for westslope cutthroat trout (WCT), other native fish species, and wildlife. It is unknown to what extent bull trout occupy the watershed, fish surveys have not documented bull trout in sampled areas. Two perched culverts located in lower East Fork Blue Creek are fish passage barriers. Genetic analysis completed on WCT inhabiting East Fork Blue Creek upstream from the culverts suggests the barriers have maintained a genetically-pure population of WCT.

The Lower Clark Fork Watershed Group (LCFWG) and their Technical Advisory Committee (TAC) requested assistance in completing a watershed assessment and restoration project prioritization plan. The TAC is comprised of representatives from the U.S. Forest Service, Idaho Fish and Game, Montana Fish, Wildlife & Parks, Avista Corp., and the LCFWG.

The assessment served two purposes; one, as a watershed assessment, it presented information on historical and existing conditions based on field data collection, remote sensing, and existing data review. Secondly, the document served as a stream corridor restoration plan that prioritized aquatic habitat improvement projects in the Blue Creek watershed. Restoration concepts were intended to enhance quatic and riparian habitat, improve fish passage, and/or decrease sediment delivery to the channel network.
