Summary
Built in 1980, this earth dam stands at a height of 22.3 feet and has a storage capacity of 52.1 acre-feet, with a normal storage level of 24.5 acre-feet. The dam is situated on TR-Snake Creek and is under the jurisdiction of the Nebraska Department of Natural Resources.
Despite its low hazard potential, Spilker Dam is regulated, inspected, and enforced by state authorities to ensure its structural integrity and safety. The dam has not been rated for its condition assessment as of the last inspection in September 2018. The surrounding area covers a surface area of 4.7 acres and has a drainage area of 0.09 square miles, making it a crucial water resource for the local ecosystem.
For water resource and climate enthusiasts, Spilker Dam represents a vital piece of infrastructure that supports various ecological and agricultural activities in Gage County, Nebraska. With its modest dimensions and multi-purpose design, the dam plays a significant role in providing water for fire protection, livestock, and aquatic life. As a state-regulated structure, Spilker Dam underscores the importance of responsible dam management and maintenance to ensure the continued sustainability of water resources in the region.

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.
