Pomperaug River Low‐Flow Operations Plan Public Notification

Pomperaug River Low‐Flow Operations Plan was developed through a collaborative effort of the Pomperaug River Watershed Coalition, the Town of Southbury and the Connecticut Water’s Heritage Village Water Division to reduce water use during low flow periods.  The plan calls for increasing levels of voluntary water conservation based on Pomperaug River flows.

The Plan uses three river flow threshold levels based on flow in the river and issues three corresponding action levels as follows:



The typical low-flow period for the Pomperaug River occurs between July 1 and October 31st. The Plan was based on earlier in-stream habitat studies that identified water-level needs for various fish species during these months which make up the rearing and growth bio-period. Given the proximity of the Heritage Village Water wells to the Pomperaug River, river flows are an early indicator that conservation measures should be encouraged to help protect fish communities while also protecting drinking water supplies. 


While the wise use of water should be practiced throughout the year, during times of low flow in the river your participation in the water conservation measures described within each Action Level will make an important difference. Thank you!
