Located in Wayne County, Iowa, the Upper Locust Creek Watershed Site L-33 is a vital water resource managed by the local government with oversight from the Iowa Department of Natural Resources. Constructed in 1995 by the USDA NRCS, this earth dam stands at a height of 23 feet and serves multiple purposes including fire protection, stock watering, small fish pond management, and flood risk reduction. With a drainage area of 0.34 square miles and a storage capacity of 114 acre-feet, this dam plays a crucial role in managing water resources in the region.

The dam's low hazard potential and moderate risk assessment make it a key component of the water management infrastructure in the area. The dam is not currently rated for condition assessment, but it is regularly inspected, ensuring its structural integrity and effectiveness in flood risk reduction. The dam's location along the TR- Locust Creek and its proximity to West Liberty, MO, highlight its importance in safeguarding local communities and ecosystems from potential water-related hazards. As a part of the larger Rock Island District managed by the USDA NRCS, this site exemplifies the collaborative efforts to sustainably manage water resources and mitigate climate-related risks in the region.
