Summary
This earth dam, primarily used for purposes other than flood control or water supply, holds a maximum storage capacity of 174 acre-feet and a normal storage of 92 acre-feet. Despite being privately owned and not regulated by the state, the dam is inspected and permitted by Texas authorities to ensure its safety and functionality.
The dam, situated on the TR-RIO GRANDE river, does not have a spillway and is classified as a high-risk structure with a hazard potential that is not currently available. The condition of the dam is not rated, and emergency preparedness measures, such as an Emergency Action Plan (EAP), have not been reported. Although the dam has no associated structures and limited drainage area, it serves as a crucial component in managing water resources in the region. Water resource and climate enthusiasts interested in the South Apache Ranch Lake Dam can explore its design characteristics and operational details to better understand its role in the local ecosystem.
With its unique design features, operational specifications, and location in the Fort Worth District, the South Apache Ranch Lake Dam is a significant structure in the water management infrastructure of Texas. While its risk assessment is categorized as high, the dam plays a vital role in regulating water flow and storage in the area. As enthusiasts delve into the details of this earth dam, they can gain valuable insights into the intersection of water resources, climate considerations, and infrastructure management.

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.
