Water Quality & Monitoring

Water quality monitoring data have been collected at various locations in the Stony Brook, Upper Lake, Lower Lake and the tributary stream to Upper Lake (Project Stream) on the Mount Holyoke campus biweekly from 1996 to present day.

The campus lake system has been identified as excessively high in certain nutrients, causing eutrophication in both Upper and Lower Lake. Through consistent water quality sampling by dedicated staff and the various student-faculty restoration efforts around campus, students are able to monitor the health of this important campus ecosystem and contribute high quality data to their own independent projects or coursework.

Long term water quality monitoring data including water temperature, dissolved oxygen content and turbidity is available on the Institutional Data Archive.

Stony Brook Water Flow Gauge

Stony Brook Water Flow Gauge

In the fall of 2018, the MWCE in conjunction with several academic departments installed a water level sensor and datalogger at the pumphouse primarily to monitor Stony Brook water flow, as it is vital for the ecological health of both Upper Lake and Lower Lake.

This sensor regularly measures the water level of Stony Brook and calculates the flow, and also has air temperature sensors and a rain gauge.
