This data is out of date, no longer updated, and may contain inaccurate information, please see Salmonid Population Monitoring Areas - California - CMP [ds3001].The California Monitoring Plan is the most comprehensive program to date that provides a complete understanding of Californias salmon and steelhead populations, utilizing statistically-rigorous modeling in combination with a variety of in-river sampling and surveys methods. CDFW and NOAA Fisheries are leading the implementation of this Plan from Californias northern border with Oregon south to its board with Mexico. This monitoring strategy was designed to estimate populations of anadromous salmonids in coastal streams, and is being currently expanded to include the anadromous rivers of Central Valley.For more detail on the Klamath-Trinity River systems, visit the links below.https://www.wildlife.ca.gov/Conservation/Fishes/Chinook-Salmon/Anadromous-Assessment
