With a height of 35 feet and a storage capacity of 122,800 acre-feet, the dam serves multiple purposes including fish and wildlife pond management, recreation, and water supply. The controlled spillway, with a width of 2,682 feet, helps manage water levels during peak flow events.
The dam has a high hazard potential and is subject to regular inspections and risk assessments to ensure its structural integrity. Emergency management measures are in place to mitigate flood risks, including an Emergency Action Plan (EAP) and coordination with local authorities for emergency response. The US Army Corps of Engineers continuously monitors and maintains the dam to address potential risks and ensure public safety. Despite its risk management efforts, the dam's capacity to store water is limited, and extreme weather events can lead to dam releases or operational challenges.
Overall, Lac Qui Parle Dam plays a crucial role in managing flood risks and protecting the surrounding area from potential flooding events. With ongoing risk assessment and maintenance efforts, the dam remains a critical infrastructure for water resource management and climate resilience in the region.
