Information related to water conditions is essential to enhancing the visitor experience and safety. In 2018, a partnership between the National Marine Sanctuary Foundation and Maryland Department of Natural Resources provided for the purchase and operation of a new water quality buoy adjacent to Mallows Bay. The buoy operates from April through October and reports real-time measurements of water temperature, salinity, oxygen, and other parameters that inform recreational and commercial users of the sanctuary.

Beginning in summer 2020, a new partnership between the National Marine Sanctuary Foundation and the Potomac Riverkeeper Network will create a citizen science monitoring program at Mallows Bay. The monitoring program will focus on bacterial contamination in the water, which is important to human health.
