Summary
Constructed in 1960, this earth dam stands at a height of 20 feet and stretches 380 feet in length, providing a storage capacity of 191.8 acre-feet. With a primary purpose of flood risk reduction, Andrews Dam 3664 is regulated by the Nebraska Department of Natural Resources and is subject to regular inspections to ensure its structural integrity and safety.
Despite its low hazard potential, the condition assessment of Andrews Dam 3664 remains unrated as of the last inspection in June 2017. The dam's emergency action plan status, risk assessment, and inundation maps preparation are also not specified in the available data. However, with its crucial role in mitigating flood risks in the area, ongoing monitoring and maintenance are essential to safeguard the surrounding communities and water resources. As water resource and climate enthusiasts, staying informed about the maintenance and management of Andrews Dam 3664 is key to understanding its impact on local ecosystems and the broader hydrological landscape.

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.
