7/12/2022 - Pomperaug River Low-Flow Plan Action Level Reached

Second threshold, “Water Conservation Desired” reached
People in the Pomperaug Basin asked to voluntarily conserve water

River flows in the Pomperaug River have hit the second threshold in the 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 are asking residents 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. Customers of the Connecticut Water’s 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. Private wells and public water supplies in the area draw water from the Pomperaug Aquifer, which can affect river flows.

The typical low-flow period for the Pomperaug occurs between July 1 and October 31st, and this is the kind of scenario that was envisioned when the low-flow operations plan was implemented in 2019. The current river flow is 13.3 cubic feet per second (cfs), which is below the second threshold of 15 cfs. The final threshold, which would reinforce the desire for conservation, would be when the flows are less than 7 cfs.
