Lake Galena is a reservoir in Peace Valley Park, Pennsylvania, in the United States, created in 1974[2] by the damming of the north branch of the Neshaminy Creek.

Before that time, much of the lakebed had been part of the village of New Galena, the economy of which was based largely on farming.

[3] Mining of galena (in addition to small amounts of zinc, silver, copper and gold[3]) had been mildly successful since the property was purchased in 1861.

[3] The lake is supplemented by water from the Delaware River Point Pleasant Diversion Project for the purpose of augmenting public drinking water supplies for approximately 150,000 people in Bucks and Montgomery counties.

[4] The water supply intake is downstream of the dam at the confluence of Pine Run and North Branch Neshaminy Creek.
