Summary
With a height of 34 feet and a length of 310 feet, the earth dam serves the primary purposes of fire protection, stock, and small fish pond. It has a storage capacity of 90 acre-feet and covers a surface area of 5.5 acres, with a drainage area of 0.43 square miles. The dam is regulated by the Iowa Department of Natural Resources and is subject to state permitting, inspection, and enforcement.
The Jungman Dam is situated on the TR-Raccoon River in West Des Moines, Iowa, and falls under the jurisdiction of the Rock Island District of the US Army Corps of Engineers. Despite its low hazard potential and moderate risk assessment, the dam's condition remains unrated, with no recent inspection date provided. The spillway type is listed as uncontrolled, with no outlet gates or associated structures mentioned. While the dam has not been modified in recent years, it is important for water resource and climate enthusiasts to monitor its maintenance and risk management measures to ensure the safety of the surrounding community and environment.
In the event of an emergency, it is crucial for the owners of Jungman Dam to have an Emergency Action Plan (EAP) in place that meets guidelines and includes up-to-date emergency contacts. With its strategic location and critical role in water resource management, the dam serves as a valuable asset for fire protection and wildlife habitat while highlighting the importance of proper regulation and maintenance practices in safeguarding water resources and mitigating potential risks associated with dam infrastructure.

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.
