Okanogan Basin Monitoring And Evaluation Program (OBMEP)

The Okanogan Basin Monitoring and Evaluation Program (OBMEP) is a monitoring program created in 2004 within the Confederated Colville Tribes' Fish and Wildlife Department and is funded primarily by the Bonneville Power Administration through the Columbia Basin Fish Accords. OBMEP collects long-term data on salmon and summer steelhead and respective habitats in the Okanogan River Basin, including the Canadian portion.

OBMEP has created an interactive webpage to display and share the data that has been collected over the years. All of OBMEP's reports and data links are presented on which allows data to be queried, displayed in graphs and tables and downloaded. A username and password is required to query the data but anyone can easily create a login.
