Located in Danbury, Iowa, Crawford Creek Subwatershed Site 4-1 is a vital water resource managed by the local government. Designed by USDA NRCS and regulated by the Iowa DNR, this site serves multiple purposes including fire protection, stock, and small fish pond, as well as flood risk reduction. The earth dam, with a height of 39 feet and a length of 869 feet, was completed in 1976 and has a storage capacity of 135 acre-feet.

With a drainage area of 0.44 square miles, Crawford Creek Subwatershed Site 4-1 has a low hazard potential and a moderate risk rating. The dam has not been inspected for condition assessment and does not have an emergency action plan prepared. Despite these shortcomings, the site plays a crucial role in managing water resources in the area and serves as a key component in flood risk reduction efforts. Enthusiasts of water resources and climate will find this site an intriguing case study in water management and infrastructure development.
