Summary
This structure on Cow Creek is designed for flood risk reduction and other purposes, with a height of 14 feet and a length of 652 feet. The dam has a storage capacity of 68 acre-feet and serves a drainage area of 13.1 square miles, with a maximum discharge of 242 cubic feet per second.
Managed by the Nebraska Department of Natural Resources, Cow Creek 2 has a low hazard potential and is deemed to be in satisfactory condition as of the last inspection in July 2020. The dam has a hydraulic height of 12 feet and a structural height of 23 feet, providing important water resource management for the surrounding area. With its primary purpose of flood risk reduction, Cow Creek 2 plays a crucial role in safeguarding the local community from potential flooding events.
Situated in Brewster, Nebraska, Cow Creek 2 is an essential infrastructure project that contributes to water resource management in the region. With its efficient design and successful operation, this dam stands as a testament to effective collaboration between private owners and state regulatory agencies in ensuring the safety and sustainability of water resources in Cherry County.

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.
