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. Please understand that this funding process is very competitive, and most grants are awarded to well-established organizations with a strong track record of community-based water quality stewardship. 

Duration of Support: Most grants are for a one year period; however, you do not have to ask for a one year grant. It is permitted to request a shorter or longer grant period if that is what you need.

Frequency of Applying: Organizations that are funded may re-apply after one year if their evaluation form has been submitted and accepted.

You can learn more about this opportunity by visiting the funder's website.


  • To be eligible for a California Watershed Protection Fund grant, the applicant and project must meet the following criteria:
    • Projects Supported:
      • The project must be designed to benefit the water quality of the currently eligible watersheds and their ecosystems:
        • Sacramento – San Joaquin River Delta and their watersheds including American River, Feather River, and Lake Oroville
        • Southern California Bight and Los Angeles area watersheds, including Santa Ana River and San Gabriel River
        • Humboldt Bay
        • Mad River
        • San Francisco Bay
        • Monterey Bay
        • Russian River
    • Applicant requirements:
      • The applicant must demonstrate the capacity to complete the proposed project, including experience in successfully conducting similar or otherwise related work in the past.
    • Nonprofit status:
      • The applicant must be a 501(c)3 organization, fiscally-sponsored by a 501(c)3, or a governmental or tribal entity.
      • If you work with a small organization that lacks non-profit status but has a compelling project, the Rose Foundation may be willing to act as your fiscal sponsor for this grant proposal.


  • Environmental Justice:
    • While this is not specifically an environmental justice fund, supporting environmental and social justice is a core organizational value that guides all of our grantmaking.
    • Projects that advance environmental justice as well as water quality will receive preference.


  • In order to make space for new applicants, grantees who received funding within the last 12 months are discouraged from applying this round.
  • California Watershed Protection Fund Grants are not recommended for very small organizations or first-time grant seekers.
  • 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.
