The California Watershed Protection Fund, administered by Rose Foundation, supports projects that improve water quality and protect California watersheds. Funded by settlements in Clean Water Act citizen enforcement cases, it directs support toward surface water quality benefits in watersheds where enforcement actions have occurred. Eligible watersheds change by cycle as funding fluctuates.
Supported work includes water quality monitoring, restoration, green stormwater infrastructure, responses to emerging toxic and chemical threats, and community leadership linked to identifiable water quality actions. Priority goes to community-oriented grassroots groups and organizations with strong community-based water quality experience. The fund especially encourages projects involving impacted communities, benefiting vulnerable populations, and centering equity and environmental justice. Education and outreach must produce tangible water quality benefits, rather than primarily educational outcomes with limited near-term impact.
