Summary
With a height of 24.6 feet and a storage capacity of 72.8 acre-feet, this dam primarily serves the purpose of fire protection, stock, and small fish pond management. Situated on TR-West Branch Creek, the dam covers a surface area of 8.38 acres and has a drainage area of 1.22 square miles.
Despite its low hazard potential, Perry Dam 1987 has been rated as being in poor condition during its most recent inspection in March 2020. The dam is under state jurisdiction and regulation by the Nebraska Department of Natural Resources, with permitting, inspection, and enforcement all carried out by the state agency. While the dam has not undergone any significant modifications over the years, its emergency action plan status and risk assessment measures remain undisclosed. As an enthusiast interested in water resources and climate, the unique design and purpose of Perry Dam 1987 offer a fascinating case study in private dam management and the challenges of maintaining infrastructure in a changing climate.

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.
