Summary
Standing at a height of 26 feet and stretching 1368 feet in length, this dam serves a primary purpose that extends beyond traditional water storage functions. While its storage capacity reaches up to 103 acre-feet, the dam's normal storage level remains at 93 acre-feet, with a surface area of 5 acres.
Managed by the Nebraska Department of Natural Resources, Prairie Dog Hill Lagoon Dam is regulated, inspected, and enforced by the state agency to ensure its structural integrity and compliance with safety standards. With a low hazard potential and a satisfactory condition assessment as of March 2020, this dam embodies a crucial component of the local water resource infrastructure. While it does not feature a spillway or outlet gates, the dam plays a vital role in flood control and water management for the region.
As a key feature in the water resource landscape of Custer County, Nebraska, Prairie Dog Hill Lagoon Dam provides not only flood protection but also contributes to the sustainable use of water resources in the area. Its strategic location, design, and management exemplify the importance of dams in maintaining a balance between water supply, environmental conservation, and climate resilience in the region.

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.
