Summary
With a height of 26 feet and a length of 550 feet, this earth dam provides a storage capacity of 44 acre-feet and can handle a maximum discharge of 180 cubic feet per second. Despite its low hazard potential, the dam is regulated and inspected by the Nebraska Department of Natural Resources to ensure its satisfactory condition.
Owned by the local government and designed by the Natural Resources Conservation Service, Coover Dam 2389 plays a crucial role in managing water resources in the region. Its primary purpose includes flood risk reduction, and it has a normal storage capacity of 4 acre-feet. The dam is situated in an area with a drainage area of 2.3 square miles, providing essential protection to the surrounding community against potential flooding events. With its location in a rural setting, the dam contributes significantly to the overall water management efforts in the area.
Coover Dam 2389 stands as a testament to effective water resource management practices in Nebraska. With a strong foundation in soil and core types including buttress and stone, the dam has demonstrated its resilience over the years. Regular inspections ensure that the dam meets regulatory standards and is ready to handle any potential emergency situations. As a key infrastructure for flood protection and water storage, Coover Dam 2389 plays a vital role in safeguarding the local environment and community from the impacts of extreme weather events.

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.
