Summary
Completed in 1977, this earth dam stands at a height of 30 feet and stretches 1015 feet in length. The dam has a storage capacity of 48 acre-feet, with a normal storage level of 20 acre-feet, serving the local community in the management of water resources for agricultural activities.
Despite its low hazard potential, Peterson Dam 2 has been rated as having poor condition as of the last assessment in June 2019. The dam is regulated by the Nebraska Department of Natural Resources, ensuring that it meets state inspection and enforcement standards. With a drainage area of 0.1 square miles and a maximum discharge capacity of 82 cubic feet per second, the dam plays a crucial role in managing water flow in the TR-SPRING CREEK and supporting the surrounding agricultural landscape.
As water resource and climate enthusiasts, the data on Peterson Dam 2 highlights the importance of infrastructure maintenance and monitoring to ensure the safety and efficiency of water management systems. With its role in irrigation and water storage, this dam serves as a vital component of the local ecosystem, emphasizing the need for continued oversight and investment in sustainable water resource practices in Nebraska.

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.
