Innes Jalas Subwatershed Site 3-1, located in O'Brien County, Iowa, is a locally owned earth dam constructed in 1966 by the USDA NRCS for multiple purposes including fire protection, stock watering, and small fish pond creation. This dam plays a crucial role in flood risk reduction along TR-Murray Creek, with a storage capacity of 19 acre-feet and a drainage area of 0.2 square miles. Despite its low hazard potential and moderate risk assessment, the dam has not been rated for its current condition and lacks an Emergency Action Plan, indicating a need for continued monitoring and maintenance.

Owned and regulated by the local government, this dam falls under the jurisdiction of the Iowa Department of Natural Resources, with state-permitted inspections and enforcement in place to ensure its safety and compliance. The dam's primary purpose is to provide essential water resources for the surrounding area while also serving as a protective measure against potential flooding events. With a spillway width of 0 and no outlet gates, the dam's design reflects its intended use for controlled water storage and management within the subwatershed.

As a vital component of the local water resource infrastructure, Innes Jalas Subwatershed Site 3-1 stands as a testament to the collaborative efforts between government agencies and the community to sustainably manage water resources in the region. By maintaining a proactive approach to monitoring and addressing any potential risks or deficiencies, stakeholders can ensure the long-term functionality and safety of this essential piece of infrastructure for both current and future generations.
