Summary
Completed in 1972, it serves the primary purpose of flood risk reduction on Stump Creek. With a dam height of 41 feet and a drainage area of 10.1 square miles, the dam has a storage capacity of 2842 acre-feet and a maximum discharge of 4700 cubic feet per second. Despite its low hazard potential and satisfactory condition assessment, the dam is subject to state regulation and inspection by the Nebraska Department of Natural Resources.
The dam's structure consists of stone core and soil foundation, with a hydraulic height of 40 feet and a structural height of 42 feet. It has a length of 1208 feet and a surface area of 5 acres. The dam is located in a rural area near Cozad, Nebraska, and is under the jurisdiction of the Kansas City District of the US Army Corps of Engineers. The last inspection in May 2019 deemed the dam to be in satisfactory condition, with an inspection frequency of every 5 years.
While Spring Creek 25-A may not pose a high risk, it plays a crucial role in managing flood risks in the area and protecting downstream communities. Water resource and climate enthusiasts can appreciate the engineering and regulatory efforts that go into maintaining the safety and functionality of this essential infrastructure for flood control and water management in Nebraska.

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.
