California Watershed Protection Fund

About the Fund

The California Watershed Protection Fund supports projects designed to benefit the 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. We anticipate that this funding process will be very competitive and most grants awarded will be in the $7,500 – $25,000 range. While the Rose Foundation welcomes proposals from small grassroots conservation and environmental justice groups, most grants are awarded to well-established organizations with a strong track record of community-based water quality stewardship. If your organization is new or small (under $100,000 annual expenses), we urge you to consider applying to our Northern California Environmental Grassroots Fund instead.
