Summary

With a height of 18 feet and a length of 462 feet, the dam holds a maximum storage capacity of 61 acre-feet and covers an area of 6 acres. The dam, regulated by the Nebraska DNR, is inspected regularly and was last assessed to be in satisfactory condition in June 2016.

Situated on TR-ELK CREEK in Oak, Nebraska, Frahm Dam 1654 plays a crucial role in managing water resources for irrigation in the region. The dam's location at SWS32T3R6W allows for the storage of water for agricultural use, with a drainage area of 0.3 square miles and a normal storage capacity of 27 acre-feet. With a hydraulic height of 16 feet and a structural height of 21 feet, the dam ensures reliable water supply for the surrounding area.

Managed by the Natural Resources Conservation Service, Frahm Dam 1654 is an essential infrastructure for water resource management in Nebraska. With its stone core and soil foundation, the dam provides essential water storage and discharge capabilities for the efficient irrigation of agricultural lands in the region. Despite its age, the dam continues to fulfill its purpose effectively, contributing to the sustainable use of water resources in the area.

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.
