Pachaug Pond is located in the town of Griswold. It is an artificial impoundment in the Thames River Drainage Basin and is the state’s largest lake east of the Connecticut River. The watershed is 33,408 acres of mostly woods or wetland with some agricultural and very little urban development. The pond is fec by the Pachaug River from Glasgo Pond, and by Burton Brook, Billings Brook and several small intermittent streams. The lake drains northward into the Pachaug River. The shoreline is wooded with a moderate amount of residential development along most of the shoreline. Approximately 1 mile of the northeast shoreline is within Pachaug State Forest and is undeveloped woods.

The transparency of the lake is turbid with visibility of 5 ft. in the summer, reduced by tea- colored stain. The bottom of the lake consists of fine sand, silt and organic muck. The fishing should be fair to good for most species.
