Keller Lake, located in St. Paul, Minnesota, is a picturesque body of water fed by Keller Creek. Built in 1938 by the Works Progress Administration (WPA-C-PB), this gravity dam stands at 12 feet high and spans 50 feet in length. With a storage capacity of 450 acre-feet, the lake covers a surface area of 72 acres and serves as a vital resource for the local community.

Managed by the Minnesota Department of Natural Resources, Keller Lake is regulated, permitted, inspected, and enforced to ensure its safety and functionality. Despite its low hazard potential and satisfactory condition assessment, the dam undergoes regular inspections every eight years to uphold its reliability. With a maximum discharge capacity of 1350 cubic feet per second, the dam plays a crucial role in flood control and water management in the region.

Water and climate enthusiasts will appreciate Keller Lake not only for its historical significance but also for its essential role in maintaining the ecological balance of the area. As a key structure in the watershed, this dam exemplifies the importance of sustainable water resource management and serves as a reminder of the interconnectedness between human infrastructure and natural ecosystems.
