Jett Subwatershed Site 2-1 is a crucial flood risk reduction infrastructure located in Woodbury, Iowa, along the TR- EAST BRANCH river. This earth dam, constructed in 2002 by the USDA NRCS, stands at a height of 33 feet and spans 386 feet in length. With a storage capacity of 42 acre-feet and a surface area of 2.5 acres, this dam plays a pivotal role in managing water flow and mitigating flood hazards in the region.

Managed by the Iowa DNR, Jett Subwatershed Site 2-1 is designed to withstand moderate risks and has a low hazard potential. While not currently rated for condition assessment, this site meets state regulations for permitting, inspection, and enforcement. The dam's spillway is uncontrolled, with a width of 2 feet, and it serves as a critical element for ensuring the safety and integrity of the structure during high water events.

This site, owned by the local government and primarily funded by the Natural Resources Conservation Service, exemplifies collaborative efforts to protect the surrounding community from flooding. With its strategic location and design features, Jett Subwatershed Site 2-1 stands as a testament to effective water resource management and climate resilience in Iowa.
