The Continued Need for Connectivity
For eons, presence of migrating anadromous fish at almost all times of year enriched ecosystems and sustained countless generations of indigenous communities. Today, barriers to migration, overharvesting and climate change have led to major declines in California salmonid populations, with Moyle et al estimating that 45% of populations are at risk of extinction within 50 years, and 74% at risk of extinction within 100 years if current trends continue.
Preserving intact waterways and habitats, removing fish passage barriers, researching and monitoring our efforts, and communicating the need for continued restoration will help give California’s anadromous fish a fighting chance.
The Power of Partnership
The California Fish Passage Forum provides a dedicated space for our member organizations to share the efforts of their fish passage projects and programs, and bring their collective expertise to guide investment in assessment, implementation and monitoring of fish passage improvement.
Membership is open to organizations working to restore fish passage in historically anadromous CA waters. Members participate in committee work, utilize the Passage Assessment Database where applicable, guide restoration investment through the Forum funding opportunity, share their technical expertise, and communicate the work within their organization back to the full Forum Steering Committee.
More than just Salmonids
For migratory species like Pacific Lamprey, massive white and green sturgeon, and the endemic potadromous Clear Lake Hitch, recovery depends on restoring aquatic connectivity and functional riparian and riverine habitat.
The California Fish Passage Forum recognizes the need for multi-species habitat restoration, and supports assessing, funding, and raising awareness of the needs of California’s diverse migratory fish species.
Annual Funding Opportunity
Annually, the Forum receives funding from the National Fish Habitat Partnership for the support of projects that help the Forum meet its mission and goals. The small competitive grants programs typically ranges from around $10,000-$50,000 for smaller planning or assessment efforts to over $100,000 for complex dam removal or multi-phase design and construction projects.
The Forum is committed to investing in sometimes hard-to-fund aspects of fish passage projects, including watershed and barrier assessment, research, monitoring and project evaluation.
Fish Passage Science and Data
The Forum Science and Data Committee, supports the collection and management of fish passage restoration data, provides trainings on assessment of fish passage barriers, and supports updates to the Passage Assessment Database (PAD).
The PAD is an ongoing map-based inventory of assessments of anadromous fish passage in California. It is an important tool for determining and tracking the outcomes of passage improvement projects. The PAD compiles data from more than one hundred agencies, organizations, and landowners throughout California, and allows past and future barrier assessments to be standardized and stored in one place.
Indigenous Lead Restoration
From time immemorial, indigenous peoples tended California’s abundant natural resources using Traditional Ecological Knowledge to support the health of forest, salmon, lamprey, elk, oak, and countless other sources of food, fuel, wood and fiber. Today, tribes are working to recover from the lasting impacts of forced relocation, cultural suppression and criminalization of traditional resource management practices.
There is a growing movement of indigenous-lead fisheries restoration, where tribal governments, coalitions and nonprofits are critical partners in restoration and management of California’s shared natural resources.
Supporting Restoration
Neefus Gulch Coho Salmon Barrier Removal — North Fork Navarro River, Mendocino County (Forum Funded in 2018 for $39,513)
The Forum invested in the design of an improved road-stream crossing, as part of a series of improvements from TU, culminating in a 2024 earthen dam removal and the return of spawning coho to habitat absent of fish for 70 years — part of a record 30,000+ CCC coho return in 2024-25.
Supporting Restoration
Benbow Dam Removal — South Fork Eel River, Humboldt County (Forum funded in 2017 for $58,499)
The Forum invested in the second-largest concrete dam removal in California at the time, with the partnership between California Department of Parks and Recreation, NOAA, and other agencies. The project opened 100+ miles of South Fork Eel River to unimpeded fish passage.
Supporting Restoration
Santa Margarita River Fish Passage and Bridge Replacement — Santa Margarita River, San Diego County (Funded in 2020 for $47,410)
The Forum invested in the replacement of the last remaining fish passage barrier on the mainstem Santa Margarita River with a full-span bridge to restore migration access for endangered Southern California Steelhead, opening 12 miles of upstream spawning and rearing habitat approximately two miles north of Fallbrook in San Diego County.
Supporting Restoration
Jenny Creek Man-Made Barrier Removal — Klamath River, Siskiyou County (Funded in 2024 for $100,000)
The Forum invested in the removal of a barrier on Jenny Creek, the largest tributary in the hydroelectric reach of the Klamath River, which was blocked to anadromous fish for over 60 years, first by Iron Gate Dam and then by its own concrete man-made barrier 1.05 miles upstream of the former reservoir. The removal was timed strategically to coincide with the historic removal of the four Klamath River mainstem dams in 2024 — the largest dam removal project in world history.
About the Forum
The California Fish Passage Forum is a collaborative partnership of researchers, engineers, fisheries and restoration practitioners and advocates working within the state agencies, federal agencies, nonprofits, and tribes to protect and restore California anadromous waterways. The forum members work collaboratively to understand the state of fish passage improvement projects and programs, direct investments into restoration, research, assessment and monitoring, and develop data products, trainings, and media materials to communicate the continued need for restoration. The Forum is a congressionally recognized Fish Habitat Partnership supported by the National Fish Habitat Partnership (NFHP).
Our Impact
Partnership
14 member organizations, including federal agencies, state agencies and nonprofits.
Funding
So far, the Forum has invested almost $2 million, helping to leverage an additional $350 million from agency partners including NOAA, DWR, CDFW and many others. The Forum funding opportunity represents a comparatively small but important contribution for helping projects reach their cost share needs.

The California Fish Passage Forum is one of 20 Fish Habitat partnerships recognized under the National Fish Habitat Partnership. The mission of the National Fish Habitat Partnership is to protect, restore, and enhance the nation’s fish and aquatic communities through partnerships that foster fish habitat conservation and improve the quality of life for the American people. NFHP supports the work of the diverse network of fish habitat partnerships, and produces independent data products to assess the state of Americas freshwater and marine fish populations and habitats through the National Assessment.
Fish Habitat Partnerships operating in California include the California Fish Passage Forum, Pacific Lamprey Conservation Initiative (PLCI), the Pacific Marine and Estuarine Partnership (PMEP), and the Western Native Trout Initiative (WNTI).
