Summary
Completed in 2018, this earth dam with stone core stands at a height of 57 feet, serving a primary purpose of 'Other' with a storage capacity of 50 acre-feet. The dam's low hazard potential and satisfactory condition make it a crucial component in managing water resources in the region.
With a drainage area of 0.01 square miles and a surface area of 3.35 acres, Cat Creek Lagoon Dam plays a vital role in controlling water flow and storage. Its proximity to the tributary of Cat Creek highlights its importance in maintaining the local ecosystem and water supply. Regular inspections by state authorities ensure its structural integrity and adherence to regulatory standards, guaranteeing its effective function in water resource management.
As a relatively new structure, Cat Creek Lagoon Dam continues to contribute to the sustainable management of water resources in Custer County, Nebraska. Its completion in 2018 marked a significant milestone in enhancing water storage and flow regulation in the area, showcasing the importance of private dam ownership in supporting climate resilience efforts.

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.
