This site, designed by the USDA NRCS, serves multiple purposes including fire protection, stock watering, and small fish pond maintenance. Built in 1975, the earth dam stands at a height of 52 feet and has a storage capacity of 320 acre-feet to regulate the flow of the TR-West Fork Little Sioux River.
With a low hazard potential and moderate risk assessment, the Windy Hill Subwatershed Site 5-3 plays a crucial role in flood risk reduction for the surrounding area. The dam has not been rated for its condition assessment, and there are no recent inspection dates available. Despite this, the site meets state regulatory standards and is subject to regular inspections, permitting, and enforcement by the Iowa DNR. The dam's primary purpose highlights its importance in safeguarding the local ecosystem and community against potential water-related emergencies.
