Summary
This dam, with a height of 32 feet and a length of 580 feet, serves multiple purposes including flood risk reduction and storage. With a normal storage capacity of 14 acre-feet and a maximum storage capacity of 117 acre-feet, the dam plays a crucial role in managing water resources in the area.
The dam, situated on TR-Larrabee Creek, is regulated by the Nebraska Department of Natural Resources and undergoes regular inspections to ensure its structural integrity. With a low hazard potential and a satisfactory condition assessment as of May 2020, Glen Forney Dam continues to provide essential water management services to the surrounding community. Despite its low hazard potential, the dam is equipped with emergency action plans and updated emergency contacts to mitigate any potential risks.
As part of the Omaha District, Glen Forney Dam contributes to the overall water infrastructure in the region, with a drainage area of 7.2 square miles and a maximum discharge capacity of 765 cubic feet per second. Its presence underscores the importance of sustainable water resource management and climate resilience in Nebraska, showcasing the collaboration between private owners and government agencies in safeguarding water supplies and reducing flood risks.

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.
