The Okanogan Basin Monitoring and Evaluation Program (OBMEP) is a monitoring program created in 2004 that collects long-term data on salmon and summer steelhead and respective habitats in the Okanogan River Basin.
The primary goals of OBMEP are:
- Assess the status and trend of natural origin abundance of fish populations for various life stages.
- Assess the status and trend of juvenile abundance and productivity of natural origin fish populations.
- Assess the status and trend of spatial distribution of fish populations.
- Assess the status and trend of diversity of natural and hatchery origin fish populations.
- Monitor and evaluate tributary habitat conditions that may be limiting achievement of biological performance objectives.
OBMEP is a program within the Confederated Colville Tribes' Fish and Wildlife Department and is funded primarily by the Bonneville Power Administration through the Columbia Basin Fish Accords.
