Bloomer Dam, located in Columbus Junction, Iowa, along Goose Creek, is a privately owned structure with a primary purpose of fire protection and serving as a stock or small fish pond. Constructed in 1972 by the USDA NRCS, this earth dam stands at a height of 25 feet and has a length of 371 feet, providing a storage capacity of 50 acre-feet. With a low hazard potential and a moderate risk assessment, the dam is state regulated by the Iowa DNR and undergoes regular inspections, permitting, and enforcement to ensure its safety and functionality.

Despite its relatively small size and low hazard potential, Bloomer Dam plays a crucial role in water resource management in the region. The dam's presence helps in fire protection and serves as a water source for livestock and fish, contributing to the overall ecological balance of the area. With a surface area of 2.8 acres and a drainage area of 0.09 square miles, the dam has a normal storage capacity of 25 acre-feet, providing a reliable water source for various purposes in the vicinity.

As a part of the Rock Island District in Iowa, Bloomer Dam represents a significant engineering feat that combines both functionality and environmental conservation. With its uncontrolled spillway type and soil foundation, the dam has been a vital component of the local water infrastructure for almost five decades. Its risk assessment as moderate underscores the importance of continued monitoring and maintenance to ensure its resilience in the face of climate change and evolving water resource management challenges.
