Chinook = fall Chinook only
0 = fish or redds not detected
NA = species not found in the watershed
ND = species not monitored
ID = monitoring temporally and/or spatially incomplete

Currently, there is no standard, comprehensive monitoring program implemented in California. However, a number of efforts attempt to determine how many salmon and steelhead return to our coastal streams, as described below.
California Coastal Monitoring Program
The California Coastal Salmonid Monitoring Plan (CMP) is the current monitoring strategy for tracking the status, trends and recovery of coastal California populations of salmon and steelhead. The CMP is in its infancy and adding watersheds to the program on an ad hoc basis. Over time, provided there is enough funding, the CMP will provide robust and high-quality estimates of all salmon and steelhead coastal populations in California. It is a joint effort of the California Department of Fish and Wildlife and the National Marine Fisheries Service. See CMP.
Klamath Basin Megatable
The California Department of Fish and Wildlife annually prepare the fall and spring Chinook spawner escapment, in-river harvest and run-size estimates (called the megatables) for the Klamath-Trinity basin. Population estimates/counts are developed by the California Department of Fish and Wildlife, with support of the US Fish and Wildlife Service, Yurok Tribe, Karuk Tribe, Hoopa Valley Tribe, US Forest Service, Mid-Klamath Watershed Council, Salmon River Restoration Council, Siskiyou County Schools and Siskiyou Resource Conservation District. Estimates include natural spawners, hatchery returns, and in-river harvest.
In addition to the California Department of Fish and Wildlife, many agencies and organizations monitor salmon and steelhead in their specific watersheds. Entities that provided data for the Salmon Snapshots include: Sonoma County Water Agency, Marin Municipal Water District, Monterey Peninsula Water Management District, Casitas Municipal Water District, United Water Conservation District, US National Park Service, University of California Cooperative Extension, Resource Conservation District of the Santa Monica Mountains, and Mattole Salmon Group.
Watershed groups and local agencies are encouraged to follow the CMP monitoring protocols so that consistent, cohesive and comparable data are collected, allowing for salmon and steelhead population trend estimates statewide.
Local landowners and local citizens can help by allowing access to streams on their property and volunteering to help with spawning surveys.
