Completed in 1974, this earth dam stands at 40 feet high with a length of 510 feet, providing a storage capacity of 66 acre-feet. Situated on the TR-MAPLE RIVER, it serves flood risk reduction efforts within its 0.47 square mile drainage area.
With a low hazard potential and a moderate risk assessment score, Crawford Creek Subwatershed Site 13f-1 is regulated by the Iowa DNR and subject to state permitting, inspection, and enforcement. Although not currently rated for condition, this dam has not been modified since its completion and lacks an Emergency Action Plan (EAP). While the spillway remains uncontrolled, the structure's primary purpose and design align with sustainable water resource management practices, making it a valuable asset for the community and the environment.
