Summary
Completed in 1962, this earth dam stands at a height of 17 feet and has a hydraulic height of 16 feet. The dam's primary purpose is to provide irrigation water storage for the surrounding area, with a normal storage capacity of 39 acre-feet and a maximum storage of 97 acre-feet.
Despite its low hazard potential, Corman Dam has been assessed to be in poor condition as of the last inspection in April 2020. The dam spans 315 feet in length and is situated on TR-SPRING CREEK, regulated by the Nebraska Department of Natural Resources. With a drainage area of 0.5 square miles and a surface area of 10 acres, the dam also serves to control water flow and prevent flooding in the region.
While Corman Dam has not been modified in recent years and has no associated structures, it is crucial to monitor and maintain its condition to ensure the safety of the surrounding community and the integrity of the water resource system. As water resource and climate enthusiasts, understanding and supporting the proper management of dams like Corman is essential for sustainable water usage and environmental stewardship in Nebraska.

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.
