Summary

Owned privately, the earth dam stands at 16.1 feet in height with a storage capacity of 64.6 acre-feet. Despite its low hazard potential, the dam's condition assessment in 2017 was rated as poor, signaling a need for maintenance and upkeep.

Operated under the jurisdiction of the Nebraska Department of Natural Resources, Reesman Dam 8604 is subject to state regulation, permitting, inspection, and enforcement. Although its primary purpose is listed as 'Other,' the dam primarily serves flood risk reduction in the region. The surrounding area boasts a drainage area of 0.3 square miles and a surface area of 6.6 acres, making it a vital water resource for the local ecosystem and community.

With a designated inspection frequency of 5 years, the dam's condition and safety are closely monitored. The structure's poor condition assessment highlights the importance of ongoing maintenance and risk management measures to ensure the continued safety and efficacy of Reesman Dam 8604 for both flood control and water resource management in the region.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
