Situated in Freeburg, Minnesota, Crooked Creek R-3, also known as South Fork Lake, is a local government-owned Earth dam designed by USDA NRCS in 1968 for flood risk reduction along the Crooked Creek South Fork. This dam stands at a height of 50 feet with a structural height of 60 feet and a length of 756 feet, providing a storage capacity of 1202 acre-feet and serving a drainage area of 15 square miles. Despite being classified as having a low hazard potential, the dam's condition assessment in 2016 deemed it to be in satisfactory condition.

Managed by the Minnesota Department of Natural Resources, Crooked Creek R-3 undergoes inspections every 8 years, with the most recent one conducted in July 2020. The dam's emergency action plan status, risk assessment, and inundation maps readiness are currently unspecified. With a moderate risk level of 3, the dam's risk management measures and detailed risk characterization are yet to be determined. Overall, Crooked Creek R-3 serves as a vital infrastructure for flood control in the region, contributing to the water resource management efforts in Houston County, Minnesota.
