Summary
Constructed in 1978 by the USDA NRCS, this earth dam stands at 47 feet high with a structural height of 52 feet and a length of 717 feet. The dam has a storage capacity of 499 acre-feet and serves the primary purpose of flood risk reduction in the region.
Managed by the local government and regulated by the Nebraska Department of Natural Resources, Tekamah-Mud Creek 22-A has a high hazard potential but is currently assessed as satisfactory in condition. The dam underwent its last inspection in November 2020, with an inspection frequency of once per year. Despite its age, the dam continues to effectively mitigate flood risks in the area, with a maximum discharge capacity of 5200 cubic feet per second.
Climate and water resource enthusiasts will appreciate the vital role that Tekamah-Mud Creek 22-A plays in protecting the community from flooding events. As a key piece of infrastructure in the area, this dam serves as a testament to the importance of proactive flood risk management and the collaboration between local governments and regulatory agencies to ensure the safety and resilience of water resources in Nebraska.

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.
