California Watershed Protection Fund

About the Fund

The California Watershed Protection Fund is enabled by court-ordered environmental mitigation payments. Most of the mitigation payments relate to federal Clean Water Act problems and are limited to supporting projects designed to benefit the surface water quality of many of California’s watersheds and their ecosystems. Due to funding fluctuations, the specific watersheds eligible for grants may vary – please check the list of currently eligible watersheds. Maximum grant amount of $35k with most grants expected to range between $10,000 and $30,000. All applicants must be able to demonstrate a strong track record of community-based water quality stewardship.  The Rose Foundation welcomes proposals from small grassroots conservation and environmental justice groups, but if your organization is really new or very small we urge you to consider applying to our California Environmental Grassroots Fund instead.
