Summary
Completed in 1965 by the USDA NRCS, this earth dam stands at a height of 35 feet and has a length of 555 feet. With a storage capacity of 615 acre-feet, it serves the primary purpose of flood risk reduction in the region. The dam is regulated by the Nebraska Department of Natural Resources and undergoes regular inspections to ensure its structural integrity.
Situated in the picturesque surroundings of TR-DRY CREEK, Dry Creek South 1-E plays a crucial role in managing water resources in the area. The dam has a low hazard potential and is assessed to be in satisfactory condition as of the last inspection in September 2018. Its location in the city of MCCOOK, Nebraska, under the jurisdiction of the state regulatory agency NE DNR, underscores its importance in safeguarding the local community from potential flooding events.
As an essential part of the flood risk reduction infrastructure, Dry Creek South 1-E continues to protect the region from the impacts of extreme weather events. With a design by the Natural Resources Conservation Service and support from local government ownership, this dam stands as a testament to the collaborative efforts in water resource management. Climate enthusiasts and water resource experts alike can appreciate the role of this earth dam in ensuring the safety and resilience of the community against the forces of nature.

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.
