Built in 1963 by NDSWC, this earth dam stands at a height of 29.6 feet and has a structural height of 43 feet, with a length of 1400 feet. The dam serves primarily for water supply, with a storage capacity of 4808 acre-feet and a surface area of 234 acres, drawing from a drainage area of 96 square miles.
Regulated by the NDSWC, Pheasant Lake has undergone modifications in 1991, 2000, and 2002 to enhance its hydraulic and structural integrity. The dam's spillway is of the controlled type, and it features a single valve outlet gate. With a significant hazard potential and a very high risk assessment rating, the dam is closely monitored with regular inspections, the last of which took place in May 2018. The dam's condition is currently not rated, but it remains a critical asset for water management in the region, ensuring a sustainable water supply for the community.
