History of the Coginchaug River Reservoir

The Coginchaug River Reservoir has a rich history tied to both natural development and human intervention in Connecticut’s landscape. Its story spans from Native American presence to industrial development that transformed the river system.

Origins and Development

The name “Coginchaug” comes from the local Native American language, originally referring to the Durham area before becoming the river’s name. According to local accounts, the name means “The Great Swamp,” reflecting the natural landscape of the region.

The reservoir itself developed from damming projects along the river and its tributaries. In 1848, investors constructed a major dam on Ellen Doyle Brook, a Coginchaug tributary, creating Lake Beseck. This was part of the broader development of water resources in the area.

The headwaters of the Coginchaug River begin at Meyerhuber Pond, a man-made body of water near Bluff Head. From this starting point, the river flows through the reservoir system that you can explore today.

Historical Significance

The Coginchaug River played a crucial role in Connecticut’s industrial development. Unlike some waterways used mainly for transportation, the central and northern sections of the Coginchaug were extensively utilized for industrial power.

The Starr Mill represents one important historical site along the river. It harnessed the flowing water to power machinery, demonstrating how the river supported early American manufacturing.

When you visit today, you’ll notice remnants of these historical uses. The dam systems created not just power for industry but also the scenic reservoirs you can enjoy now.

The river’s transformation from a natural waterway to an industrial resource and finally to a recreational destination tells the story of Connecticut’s relationship with its water resources through the centuries.
