NFWF is soliciting proposals under the Innovative Nutrient and Sediment Reduction (INSR) Grants program to accelerate the rate and scale of water quality improvements through the implementation of best management practices that cost-effectively reduce nutrient and sediment pollution to local rivers and streams and the Chesapeake Bay. View a PDF of the RFP here.

For the 2023 INSR program, this includes both INSR Partnership Grants supporting the coordinated and collaborative efforts of sustainable, regional-scale partnerships implementing proven water quality improvement practices more cost-effectively, as well as a new INSR Infrastructure Grants opportunity made possible through funding from the Bipartisan Infrastructure Law for projects working to implement critical natural and nature-based watershed restoration infrastructure at scale.

NFWF is requiring all prospective INSR applicants to consult with NFWF program staff prior to submitting applications no later than November 3, 2022, to ensure eligibility and competitiveness and provide constructive feedback to strengthen proposed projects, consistent with program priorities. NFWF is also hosting an applicant webinar at 2:00PM Monday, September 12 to provide general information and answer questions on the opportunity. This webinar will be recorded and subsequently posted to NFWF’s Chesapeake Bay Stewardship Fund (CBSF) website for those unable to participate.

Prospective applicants should contact Jake Reilly at or Joe Toolan at to schedule project consultations and encouraged to contact CBSF field liaisons to vet potential project ideas prior to contacting NFWF staff directly.
