Summary
This private-owned earth dam stands at a height of 17 feet and has a storage capacity of 119 acre-feet, with a normal storage level of 89.6 acre-feet. The dam is situated on the TR-LONG PINE CREEK river and is regulated by the Nebraska Department of Natural Resources, ensuring its proper inspection, enforcement, and permitting.
Despite its low hazard potential and satisfactory condition assessment, Wilke Lagoon 1 Dam plays a significant role in water management and conservation efforts in the region. The dam's primary purpose is listed as "Other," indicating its versatility in meeting various water resource needs. With a surface area of 7.9 acres and a length of 2486 feet, the dam contributes to flood control, irrigation, and water supply for the surrounding community.
Managed by a private entity, Wilke Lagoon 1 Dam exemplifies the collaboration between private ownership and state regulatory agencies in maintaining the safety and efficacy of water infrastructure. The dam's location, design, and storage capacity make it a vital component of the local water system, ensuring sustainable water supply and climate resilience for the area. As water resource and climate enthusiasts, monitoring and supporting the upkeep of dams like Wilke Lagoon 1 is essential for safeguarding our water resources and adapting to changing climate conditions.

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.
