July 15: Creating Connecticut’s Largest Lake


With an area of 8.4 square miles and over 60 miles of coastline, Candlewood Lake is the largest lake in the state of Connecticut. Located in five towns and straddling both Litchfield and Fairfield counties, its shores are also home to some of the state’s highest-priced real estate.  It has served as a recreational haven for both wealthy city-dwellers and the families of western Connecticut for decades.

A century ago, however, there was no sprawling Candlewood Lake for Connecticans to enjoy. The lake was created in the 1920s as part of an ambitious project proposed by Connecticut Light and Power (then the state’s largest electric utility) to provide a constant source of hydroelectric power for the region, using an innovative, reversible turbine to precisely control the water level of the lake.

On July 15, 1926, CL&P’s board of directors approved the master plan to create the lake, and the utility company’s agents immediately sprang into action, organizing buyouts of over 5,000 acres of land from 35 families and property owners in the area. Even though the utility was (at that point in time) given the ability to utilize eminent domain, a few landowners still refused to sell their land, resulting in a curious scenario where, today, certain patches of the lake floor still remain under private ownership.

Over the course of the following two years, 5,400 acres of forest were hand-cleared, and over 100 buildings and homesteads that made up the tiny village of Jerusalem were either moved or destroyed in order to prepare the valley for flooding. After months of slowly diverting water from the nearby Housatonic River, the new reservoir — soon christened Candlewood Lake after a nearby mountain — was deemed complete in September 1928. Today, Candlewood Lake remains one of Connecticut’s most popular recreational areas and continues to serve as an important source of hydroelectric power for the state.
