Merrill Creek Reservoir

Water type: Artificial lake
Continent: North America
Climate: Temperate

Merrill Creek Reservoir, located in Harmony Township, New Jersey in central Warren County, New Jersey, is a 260 ha artificial lake designed to hold 15 billion gallons of water that is surrounded by 120 ha of protected woodland and fields. These lands are themselves part of 8.1 km2 of open spaces.

Merrill Creek is connected to the Delaware River, about 4.8 km via a tunnel. The earthen Merrill Creek Dam, with a height of 85 m and a length at its crest of 350 m, was built in 1988 by a consortium of seven electric utilities, under the mandate of the Delaware River Basin Commission. It replaces the river water lost through evaporation in the cooling of 14 power plants.
