About ST JOHNS RIVERKEEPER INC

St. Johns RIVERKEEPER (St. Johns Riverkeeper, Inc.) is a privately funded 501(c)(3) nonprofit based in Jacksonville, Florida that serves as an independent, donor- and member-supported advocate for the health of the St. Johns River watershed. The organization conducts regular river patrols, investigates pollution, engages in policy advocacy, and provides education and community programs. The organization's EIN (59-3611338) matches public nonprofit records and filings for St. Johns Riverkeeper, confirming the profile is for the correct, active charity.

Current programmatic priorities include water policy and withdrawals, reducing nutrient pollution and sedimentation, addressing bacteria contamination in tributaries, habitat restoration, and community-facing education. Notable ongoing initiatives are the five-year "SAVe Our River’s Grasses" Expedition (launched 2023) focused on submerged aquatic vegetation, the Vertical Oyster Garden (VOG) program, the Resilient Ribault community/watershed work, and the Reunite the Rivers campaign concerning Ocklawaha/Silver Springs restoration. The organization also runs regular volunteer cleanups, boat-based field trips, and classroom programs.

In the last 2–3 years St. Johns RIVERKEEPER has been active in regional advocacy and public outreach: it hosted a State of the Watershed event in 2026, awarded education grants and expanded classroom and field-trip programming in 2025–2026, and participated in multi-party litigation and coalition work that contributed to a 2026 federal appeals court decision upholding federal wetlands protections. The organization maintains an active events calendar and volunteer program, demonstrating ongoing operations and community engagement.
