2024 Healthy Harbor report card rates Baltimore Harbor's ecosystem health as a "C", with Inner Harbor safe for swimming 80% of the time.

The 2024 Healthy Harbor report card rates Baltimore Harbor's ecosystem health as a "C," based on 2023 water quality data. While the Inner Harbor is deemed safe for swimming 80% of the time, grades vary: an "A+" near Fort McHenry, a "B-" in the Inner Harbor, and an "F" at Baltimore Peninsula. Algal blooms remain a concern, though efforts to improve water quality are underway, including reduced sewer overflows and oyster cultivation initiatives.
