Summary
Owned privately, the dam stands at 26 feet tall with a length of 232 feet, offering a storage capacity of 70 acre-feet. Situated on the TR-Little Walnut Creek, the dam is regulated by the Iowa Department of Natural Resources and undergoes regular inspections to ensure its safety and functionality. With a low hazard potential, the dam poses a moderate risk (3) and is classified as not rated in terms of condition assessment.
Managed by the Natural Resources Conservation Service, Broderick Dam serves as a vital water resource within the area, providing essential functions for both wildlife and local communities. Despite its small size, the dam plays a crucial role in maintaining water levels and supporting various activities in the region. With its earth construction and soil foundation, the dam exemplifies efficient design and engineering standards, showcasing a balance between practical use and environmental sustainability. As a key feature along the TR-Little Walnut Creek, the dam contributes to the overall hydrological system in the area, demonstrating the interconnectedness of water resources and climate factors.
With its uncontrolled spillway and moderate risk level, Broderick Dam represents a unique blend of functionality and safety measures. While not currently rated for condition assessment, the dam's regular inspections and low hazard potential ensure that it continues to operate effectively for its intended purposes. As an important component of the local water infrastructure, Broderick Dam stands as a testament to responsible water resource management and climate-conscious engineering practices, serving as a valuable asset for the surrounding community and ecosystem.

Dam Data Reference
Condition Assessment
SatisfactoryNo existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
