Summary
Completed in 1965, this earth dam stands at a height of 40 feet and has a hydraulic height of 39 feet, providing flood risk reduction for the surrounding area along Dry Creek. With a storage capacity of 1087 acre-feet and a drainage area of 6.3 square miles, this structure plays a significant role in managing water resources in the region.
Managed by the Nebraska Department of Natural Resources, Dry Creek South 1-F has a low hazard potential and is deemed to be in satisfactory condition following a recent inspection in September 2018. The dam, with a length of 680 feet and a surface area of 15 acres, serves as a vital component in the local water infrastructure, ensuring the safety and security of nearby residents from potential flooding events. With a maximum discharge capacity of 1701 cubic feet per second, this structure is well-equipped to handle high water flow during extreme weather events.
Despite its age, Dry Creek South 1-F remains a reliable asset for flood risk reduction in the region, thanks to regular inspections and maintenance. With support from the Natural Resources Conservation Service and state regulatory agencies, this earth dam continues to uphold its primary purpose effectively, safeguarding the local community from the impacts of climate change and unpredictable weather patterns. For water resource and climate enthusiasts, this structure serves as a prime example of sustainable water management practices in action.

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.
