Summary
With a primary purpose of providing fire protection, stock, or a small fish pond, this dam stands at a height of 8 feet and spans a length of 2025 feet, with a storage capacity of 249 acre-feet. Situated on the TR-Rio Grande river, this dam plays a crucial role in water resource management in the region.
Despite lacking a spillway, the dam's condition assessment is currently rated as "Not Rated" with a high hazard potential. Although it is not under state jurisdiction, the dam is permitted and inspected by the state regulatory agency. While it does not have any associated structures or outlet gates, this dam serves as a key infrastructure for water storage and conservation purposes in the area. With its location in a high-risk zone, it is essential to ensure proper risk management measures are in place to prevent any potential disasters.
As a part of the Fort Worth District, this dam serves as a vital component in the water resource management system in the region. With its historical significance and functional importance, Lamesa Ranch Dam No 1-58 stands as a testament to the collaborative efforts between private owners and government agencies in ensuring water security and environmental sustainability. Its construction by the USDA NRCS highlights the commitment towards utilizing natural resources for the benefit of the community while managing potential risks effectively.

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.
