Summary
Completed in 1973, this earth dam stands at a height of 25.4 meters with a hydraulic height of 25.4 meters and a structural height of 29.4 meters. It has a length of 298 meters and a storage capacity of 109.4 acre-feet, serving as a vital resource for water supply in the region.
Managed by the Nebraska Department of Natural Resources, Mohr Dam has a low hazard potential and an unsatisfactory condition assessment as of November 2019. Despite its critical role in fire protection and stock maintenance, the dam's inspection frequency is set at 10 years, raising concerns about its long-term maintenance and safety. With a drainage area of 4.08 square kilometers and a maximum discharge of 1031 cubic feet per second, Mohr Dam plays a significant role in regulating water flow and storage in the area.
Water resource and climate enthusiasts interested in the infrastructure of Mohr Dam will find its design and construction details intriguing. The dam, situated on TR-Ponca Creek, not only serves as a water storage facility but also contributes to the local ecosystem by creating a small fish pond. However, with an unsatisfactory condition assessment and limited inspection frequency, there is a need for increased monitoring and maintenance to ensure the dam's continued functionality and safety for the surrounding community and environment.

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.
