    Steelhead Runback - Redwood Creek

    The CalFish Abundance Database contains a significant amount of information regarding the current and historic status of California's anadromous fish. The data were collected in many different ways including: in-stream salmon carcass counts, salmon redd counts, live fish counted passing dams or weirs, and fish observed during summer snorkeling surveys. All of the data are assigned a spatial location and can be displayed on a map.

    Stream Habitat Survey - Gulch 19, Tributary to NF Ten Mile River

    Stream habitat data are measurements of physical and aquatic stream attributes used to analyze a stream's suitability for supporting salmonid populations, as part of larger and more complex watershed assessments, and to establish baseline conditions with which future assessments can measure change.

    CDFW stream inventory reports document habitat conditions and recommend options for the potential enhancement of salmonid habitat.

    Fire Perimeter Animations available by region

    Fire Perimeter slideshows are available for each hydrologic unit by clicking on a regional map. The animations display the spatial distribution of past large fires starting in 1995. The data comes from a comprehensive fire perimeter GIS layer jointly maintained by CAL FIRE, USDA Forest Service Region 5, BLM, NPS, Contract Counties and other agencies.

    The California Coastal Monitoring Program (CMP) is the most comprehensive program to date that provides a complete understanding of California’s salmon and steelhead populations, utilizing statistically-rigorous modeling in combination with a variety of in-river sampling and survey methods. The CDFW and NOAA Fisheries are leading the implementation of this Program in coastal watersheds from California’s border with Mexico north to the Oregon border, including San Francisco and Humboldt Bay tributaries.

    PAD Barrier Removal Reports available by map

    The California Fish Passage Assessment Database compiles currently available fish passage information from many different sources, allows past and future barrier assessments to be standardized and stored in one place, and enables the analysis of cumulative effects of passage barriers in the context of overall watershed health. Detailed Barrier Removal reports are now available for 2011 - 2014 through a map interface.

Featured Tool

Interactive Map - MESHR Case Study Reports
Each year restoration project monitoring is initiated for a randomly drawn subset of funded projects in Del Norte, Siskiyou, Humboldt, Mendocino, Trinity, Sonoma, Napa, and Marin counties.

Case Study reports are developed by the Monitoring and Evaluation of Salmonid Habitat Restoration (MESHR) team to give an overview of the restoration work and a summary of observations after the completed project has been through at least one winter. Explore available Case Studies with the new interactive map tool.

Chinook Salmon Monitoring in Coastal Streams of Central California
Starting in fall 2014, the California Department of Fish and Wildlife began augmenting in-stream surveys for fall-run Chinook salmon to see if they are entering coastal streams to spawn. The Department’s focus is to determine if fall-run Chinook salmon are present in coastal streams, and if so, their origin.
Read more in the informational “glossy” document Chinook Salmon Monitoring in Coastal Streams of Central California.

2014 Coastal Salmon and Steelhead Monitoring Program
California Department of Fish and Wildlife, in partnership with NOAA Fisheries, has produced an informational “glossy” document for the California Coastal Monitoring Program for salmon and steelhead. This is the most comprehensive program to date that provides a complete understanding of California’s salmon and steelhead populations, utilizing statistically rigorous modeling in combination with a variety of in-river sampling and survey methods.
