Francois, Missouri, is a private-owned recreational structure that stands as a vital water resource in the region. Completed in 1971, this Earth dam with a Buttress core type boasts a height of 53 feet and a length of 700 feet, creating a reservoir with a storage capacity of 608 acre-feet. With a surface area of 30 acres and a drainage area of 545 square miles, the dam serves as a popular spot for outdoor enthusiasts seeking leisure activities along the Primrose Creek.
Managed by the DAM AND RESERVOIR SAFETY PROG of Missouri, Lake Primrose Dam has been deemed to have a high hazard potential but maintains a satisfactory condition assessment. The dam's spillway, with a width of 10 feet, is of the uncontrolled type, allowing for the controlled release of excess water to prevent flooding downstream. Regular inspections are conducted, with the last assessment taking place in July 2017, ensuring the safety and stability of the dam for the surrounding community.
While the risk assessment for Lake Primrose Dam is rated as moderate, the dam continues to provide essential recreational opportunities, water storage, and flood control benefits to the region. With its scenic beauty and functional design, the dam stands as a testament to the importance of water resource management and climate resilience in maintaining the ecological balance of the area.
