Lake Zoar

Lake Zoar is a reservoir on the Housatonic River in the U.S. state of Connecticut. It was formed by the completion of the Stevenson Dam, which flooded an area of Oxford and Stevenson named "Pleasantvale" or "Pleasant Vale".  The towns of Monroe, Newtown, Oxford, and Southbury border Lake Zoar. The name Zoar originates from corner of Newtown and Monroe that once called itself Zoar after the Biblical city Zoara near the Dead Sea.

Lake Zoar Authority
The Lake Zoar Authority (LZA) is an organization for promoting safety on the lake and improving water quality. The members represent the four towns bordering the lake and meet on a monthly basis. Authority is granted through the Connecticut General Statutes, section 7-151a (of the 1969 supplement).

Sand Bar
The Sand Bar is an accumulation of sand close to the center of Lake Zoar. It is a popular meeting destination for all boaters alike. The depth of the water above the sand bar varies upon the generation schedule of "First Light Hydro Generation." The depth varies from 6 inches of water at its most shallow point to a foot before receiving. The area stretches about a quarter.

Fishing
Lake Zoar is not stocked yearly with fish by the Connecticut Department of Environmental Protection, but the Pootatuck and Pomperaug rivers feed into it are heavily stocked with trout, many of which eventually make their way into the lake.

Fish species
The lake contains the desirable Smallmouth Bass, Largemouth Bass, Northern Pike, White Perch, Yellow Perch, Calico Bass (Black Crappie), White Catfish (Ictalurus catus), Brown Bullhead, Rainbow Trout, and the Common Carp.

PCBs and fish consumption
Until the chemical was banned in the 70s, the Pittsfield, Mass. General Electric Factory routinely dumped PCBs into the Housatonic. Trout, catfish, eel, carp, or northern pike from Lake Zoar are unsafe for consumption while yellow perch, calico bass, rock bass, bluegill, and sunfish can be eaten sparingly and bass should be avoided by high-risk groups. In a 2008 study by the United States Department of Health and Human Services Smallmouth Bass varied between 0.35 and 0.58 ppm, suitable for one meal per month. PCB levels in the lake have fallen considerably since the 1980s.

Invasive species
Four invasive plant species exist in the lake as of a 2007 study, including Eurasian watermilfoil, Brittle waternymph, Curly leaf pondweed, and European waterclover.

As with all the Housatonic River impoundments south of Bulls Bridge, Zebra Mussels have invaded and colonized Lake Zoar.

Hiking
The Zoar Trail is a  Blue-Blazed Trail in Newtown maintained by the Connecticut Forest and Park Association.
