Bloomquist Dam, located in Oakland Mills, Iowa, was completed in 2002 by the Natural Resources Conservation Service (NRCS) for the primary purpose of grade stabilization along the TR-Troy Creek. This earth dam stands at 27 feet high and spans 280 feet in length, providing a storage capacity of 36 acre-feet for flood control and water resource management. Despite its low hazard potential and moderate risk assessment, the dam has not been rated for its current condition and lacks a formal emergency action plan.

Owned privately and not regulated by the state, Bloomquist Dam serves as a vital infrastructure for protecting the surrounding Jefferson County community from potential flooding events. With its uncontrolled spillway and stone core foundation, the dam plays a crucial role in managing the flow of water in the watershed, covering a drainage area of 0.17 square miles. Its strategic location and design by the NRCS make it an essential asset for ensuring water resource sustainability and climate resilience in the region.
