Clearwater MPG Snake River Steelhead DPS

Following pages are an analysis of ongoing monitoring programs in the MPG by TRT identified population, an evaluation of the quality of the information, and an evaluation of what would be needed to improve the monitoring and to move toward meeting NOAA Fisheries Service monitoring guidance standards.

Evaluations shown in this document are drawn from the work completed by the Columbia River Fish and Wildlife Authority through A. Byrne (IDFG) and C. Beasley et al. of the Collaborative System-wide Monitoring and Evaluation Project and through direct participation of the fish co-managers and FCRP action agencies.

This evaluation is a result of a workshop held at IDFG on March 17 in Boise, and includes edits provided by:
