Summary
Completed in 1982, this earth dam stands at a height of 40 feet and serves multiple purposes including flood risk reduction. With a storage capacity of 65 acre-feet and a normal storage level of 43 acre-feet, Thiltges Dam helps manage water flow in the TR-BEAN CREEK, contributing to the overall water resource management in the region.
Despite its low hazard potential, Thiltges Dam is regularly inspected and maintained to ensure its structural integrity and functionality. Its fair condition assessment as of April 2018 indicates a proactive approach to risk management and emergency preparedness. With a designated emergency action plan, the dam is equipped to handle potential emergencies, although further details on risk assessment and management measures are yet to be disclosed.
Situated within the Omaha District, Thiltges Dam plays a crucial role in water resource management in the area, especially in controlling water flow and reducing flood risks. With its modest dimensions and operational efficiency, this dam showcases the collaborative efforts between private owners and government agencies in safeguarding water resources and adapting to climate challenges.

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.
