Summary
Completed in 2016, this private-owned Earth dam serves a primary purpose beyond traditional flood control or irrigation. With a hydraulic height of 25.9 feet and a storage capacity of 102.3 acre-feet, the dam plays a crucial role in regulating water flow in the TR-Elm Creek watershed.
Managed by the Nebraska Department of Natural Resources (DNR), the Pigeon Ranch Expansion Lagoon Dam boasts a low hazard potential and a satisfactory condition assessment as of June 2018. The 2560-foot-long structure is complemented by a stone core foundation, ensuring its resilience against potential hydraulic challenges. Despite its relatively small drainage area of 0.01 square miles, the dam serves as a vital component in the region's water infrastructure, enhancing water quality and supporting local ecosystems.
Located in the Congressional District 03 of Nebraska, the Pigeon Ranch Expansion Lagoon Dam stands as a model for sustainable water resource management. With its efficient design, satisfactory condition, and low hazard potential, this Earth dam exemplifies the intersection of climate resilience and water conservation in the heart of the Great Plains. Its completion signifies a proactive approach to addressing water challenges and underscores the importance of private and state cooperation in safeguarding our natural resources for future generations.

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.
