Our Watershed
The 90 square mile (56,958 acre) Pomperaug River Watershed is located in west central Connecticut. The watershed is unique in that the geological history of the region helped produce a landscape similar to the fertile Connecticut River Valley.
One of the most important geological features of this watershed is the underlying stratified-drift aquifer - the predominant source of potable water in the region. The main stem of the Pomperaug River flows from the center of Woodbury through the town of Southbury, and ultimately discharges into the Housatonic River at Lake Zoar.
The Pomperaug River Watershed includes three main rivers, the Pomperaug, Nonnewaug, and Weekeepeemee, and the underground aquifer, as well as the land that encompasses these water resources. Many residents of the towns of Woodbury, Southbury and Bethlehem and many neighboring communities receive their water from the Pomperaug aquifer.
While the layers of glacially deposited sand and gravel that make up the aquifer help filter and purify the water, it is not unlimited and its quality cannot be taken for granted as residential growth, land use and development continue to challenge the health of the watershed.

State of the Pomperaug River Watershed Presentation
This State of the Watershed presentation offers a summary of the health of local streams and aquifers in the Pomperaug River Watershed through the findings of the organization's recent scientific field research. Also highlighted are strategies watershed residents can implement to maintain and improve their local water quality.
