Gilliand Dam, located in Washington County, Iowa, stands as a testament to effective water resource management and climate adaptation efforts. Built in 1972 by the USDA NRCS, this earth dam serves multiple purposes including fire protection and creating a small fish pond. With a height of 32 feet and a length of 352 feet, the dam has a storage capacity of 41 acre-feet, providing crucial water resources for the surrounding area.

Managed by a private owner and regulated by the Iowa DNR, Gilliand Dam has been deemed to have a low hazard potential and a moderate risk assessment rating. Despite not being currently rated for condition assessment, the dam continues to play a vital role in water conservation and ecosystem preservation along the TR-GOOSE CREEK river system. While the dam does not have outlet gates or a controlled spillway, its uncontrolled spillway type ensures that excess water is safely managed during heavy rainfall events.

As climate change continues to pose challenges to water resources and infrastructure, Gilliand Dam stands as a reliable structure in safeguarding against potential risks. With its strategic location and design, the dam remains a valuable asset in maintaining water security and supporting the local ecosystem. Adhering to state regulations and undergoing regular inspections, Gilliand Dam exemplifies the importance of sustainable water management practices in the face of a changing climate.
