In 1941 the Prairie Farm Rehabilitation Administration (PFRA) constructed a dam across the Dead Horse Creek, creating a man-made lake.
In 1953 the PFRA modified and raised the dam across the Dead Horse Creek creating a lake covering 2,490 feet of water with a centre line length of approximately 8700 feet, now know as Lake Minnewasta.
In 1981 the PFRA under a Federal-Provincial Agreement raised the level of the Morden dam by nine feet and raised the spillway by seven feet as well as lowering the water supply intake to the Morden Water Treatment Plant. Storage capacity of the reservoir was thus increased from 2,100 acre-feet to 3,100 acre-feet and the dependable annual yield increased from 430 acre-feet to 880 acre-feet. This would now provide enough water to meet the projected requirements of the City of Morden for many years to come.
On Wednesday, July 14th, 1982, a dedication plaque was unveiled by DREE Minister Herb Gray and Manitoba Resources Minister – Al Mackling. Also present for the ceremony were Frank Strauss, representing the general contractor and Morden Mayor – Max Friesen.
