Low-Flow Threshold II Reached - Water Conservation Desired

Pomperaug River Low-Flow Plan Action Level Reached

Second threshold, “Water Conservation Desired” reached

People in the Pomperaug Basin asked to voluntarily conserve water

(Aug. 28, 2025) – River flows in the Pomperaug River recently dropped below the second threshold in the Heritage Village water system’s low-flow operations plan. As called for in the plan, Connecticut Water’s Heritage Village water system, the Pomperaug River Watershed Coalition, and the Town of Southbury ask residents and businesses in the Pomperaug River Basin to voluntarily reduce their water use because of low flows in the river.

This is the second of three possible action levels identified in the plan. While customers of the Heritage Village system and private well owners are always encouraged to use water wisely, now that the Water Conservation Desired action level has been reached, they are being asked to voluntarily conserve water because of the impact on the Pomperaug Aquifer that can affect river flows.

The typical low-flow period for the Pomperaug occurs between July 1 and October 31, and this is the kind of scenario that was envisioned when the low-flow operations plan was developed. The current river flow is about 10.6 cubic feet per second (cfs), which is below the second trigger of 15 cfs. The next trigger, which would increase the call for conservation, would be when the flows are less than 7 cfs.
