As part of the National Estuarine Research Reserve System, the Great Bay System-Wide Monitoring Program (SWMP) produces in situ water quality data for four sites in and around Great Bay. In recent years, DataSondes deployed in the upper Lamprey River have documented dissolved oxygen concentrations that do not meet federal standards during a significant portion of the summer and fall period. These low oxygen concentrations, if they persist may have a negative effect on benthic and pelagic organisms in the river and will necessitate management action to improve water quality.
