Lake Darling Dam is an earthen embankment dam on the Souris River in the west north central United States, located twenty miles (30 km) northwest of Minot in Ward County, North Dakota.

The dam and lake are named after Jay N. "Ding" Darling, the first director of the Bureau of Biological Survey.

The Fish and Wildlife Service owns and operates the dam during normal conditions.

During flood conditions operational control is turned over to the U.S. Army Corps of Engineers according to a 1989 memorandum of understanding.

[4] During the 2011 Souris River flood, the dam's reservoir reached maximum levels and releases of 7,500 cu ft/s (210 m3/s) in early June, contributing to flooding downstream.
