Designed by the USDA NRCS, the dam stands at 27 feet high and spans 300 feet in length, with a storage capacity of 22 acre-feet. Despite its modest size, the dam plays a crucial role in managing the flow of water in the area, with a low hazard potential and a moderate risk assessment rating.
The dam features an uncontrolled spillway and is not regulated or inspected by the state, highlighting its private ownership and operation. While it has not been rated for its condition, the dam serves its purpose effectively in stabilizing grades and managing water levels in the surrounding areas. With a surface area of 2 acres and a drainage area of 0.09 square miles, Crawford Dam contributes to the overall water resource management in Washington County and provides important insights for water resource and climate enthusiasts interested in sustainable infrastructure development.
As a part of the Rock Island District, Crawford Dam is a testament to the collaborative efforts between private owners and federal agencies like the Natural Resources Conservation Service. With its strategic location and function, the dam not only serves practical purposes but also serves as a valuable case study for those interested in the intersection of water resource management, climate resilience, and infrastructure development.
