Summary
Constructed in 1959 by the USDA NRCS, this earth dam stands at a height of 32.75 feet, with a structural height of 36 feet and a length of 589 feet. It serves the primary purpose of flood risk reduction, with a normal storage capacity of 12 acre-feet and a maximum storage capacity of 232.8 acre-feet, helping to mitigate potential flood hazards in the area.
Managed by the NE DNR, Dry Creek 1-B is state-regulated and permitted, inspected, and enforced by the Nebraska regulatory agencies. The dam's hazard potential is classified as low, with a satisfactory condition assessment as of the last inspection in April 2018. Despite its age, the structure continues to effectively mitigate flood risks, showcasing the importance of ongoing maintenance and regulation to ensure its continued functionality and safety for the local community.
With a drainage area of 1.25 square miles and a maximum discharge of 5090 cubic feet per second, Dry Creek 1-B plays a crucial role in managing water resources in the region. As climate change continues to impact precipitation patterns and increase the frequency of extreme weather events, structures like Dry Creek 1-B are essential for safeguarding communities against potential flooding risks and ensuring the sustainable management of water resources in the face of a changing climate.

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.
