Lake Roland

Lake Roland is a 100-acre defunct reservoir in Baltimore County, Maryland. It was named for Roland Run, a nearby stream that feeds the lake and eventually flows into Jones Falls. It runs southeast through the city center to the Northwest Branch of the Patapsco River and the Baltimore Harbor. It is located just north of the Baltimore city limits.

The lake is contained within the bounds of Lake Roland Park, which was established in the 1920s and supervised by the newly organized Baltimore City Department of Parks and Recreation. The lake is an artificial impoundment created by a dam on Jones Falls and two smaller streams: Towson Run and Roland Run. The lake supports wildlife including Canada geese, largemouth bass, and common carp. The lake is part of the Lake Roland Historic District.
