Beinhorn Lake Dam Reservoir Report
Nearby: Pescado Tank Dam Catarina Lake Dam
Last Updated: February 13, 2026
Beinhorn Lake Dam, located in Dimmit, Texas, was completed in 1965 and serves as a vital water supply structure in the region.
Summary
This private dam, with a height of 12 feet and a length of 600 feet, primarily functions as an earth dam with a buttress core type. It has a storage capacity of 240 acre-feet, with a normal storage of 56 acre-feet, covering a surface area of 20 acres.
Although not regulated by the state, Beinhorn Lake Dam undergoes regular inspections and is permitted by the state for operation. With no spillway and a hazard potential of "Not Available", the dam poses a high risk, highlighting the importance of effective risk management measures. Despite its high-risk classification, the dam's condition remains unrated, emphasizing the need for continued monitoring and assessment to ensure the safety and stability of this crucial water resource infrastructure.

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.
