Summary
This earth-type dam stands at 41 feet high and spans 1520 feet, serving the primary purpose of flood risk reduction since its completion in 1972. With a storage capacity of 6207 acre-feet and a drainage area of 21.4 square miles, the dam plays a crucial role in managing water flow and protecting the local community from potential flooding events.
Located in Dawson County, Nebraska, the dam on Spring Creek (Strever) Creek is under the jurisdiction of the Kansas City District and falls within the purview of local government ownership. With a significant hazard potential and satisfactory condition assessment, Spring Creek 11-A 303 has undergone regular inspections, with the most recent conducted in March 2020. Despite its age, the dam continues to meet regulatory standards and plays a key role in safeguarding the surrounding area from potential water-related risks.
For water resource and climate enthusiasts, Spring Creek 11-A 303 offers a fascinating case study in effective flood risk reduction infrastructure. With a comprehensive design by the USDA NRCS, state regulation by the NE DNR, and a strategic location in LEXINGTON, Nebraska, this dam exemplifies the importance of proactive water management in mitigating natural disaster risks. As climate change continues to impact water patterns and intensify extreme weather events, structures like Spring Creek 11-A 303 play a crucial role in enhancing resilience and protecting communities from the adverse effects of flooding.

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.
