Neustrom Subwatershed Site 9-3, located in Woodbury, Iowa, is a critical water resource management site designed by USDA NRCS and regulated by the Iowa DNR. This earth dam structure, completed in 1971, serves multiple purposes including fire protection, stock, small fish pond, and flood risk reduction. With a dam height of 50 feet and a storage capacity of 406 acre-feet, the site covers a drainage area of 0.53 square miles along TR-Wolf Creek.

Despite its low hazard potential, the site has a moderate risk assessment rating of 3, emphasizing the importance of regular inspections and maintenance. The dam's condition assessment is currently marked as "Not Rated" and there is no specified inspection frequency or emergency action plan in place. However, the site's strategic location and design make it a valuable asset for water resource management and climate resilience in the region.
