MRA volunteers monitor water clarity and dissolved oxygen concentrations at ten mainstem sites and twelve creek or cove sites between April and October. Results are reported in the Magothy River Index.  Those interested in helping with monitoring should contact Dr. Sally Hornor.

The Magothy Clearwater Program at Anne Arundel Community College Environmental Center tracks bacterial water quality by monitoring the presence of enterococci at bathing beaches and piers between May and August. Enterococci are bacteria found in the fecal waste of birds and mammals but they do not reproduce in natural waters so their presence indicates recent fecal contamination of waterways. For results over the past 10 years and an application to participate, see Dr. Tammy Domanski’s website at AACC. Generally bathing water quality is good in the Magothy except for 48 hours after a heavy rain. Residents are advised to stay out of the water until it clears up after a rain and to stay out of the water if they have open cuts.
