Summary

Built in 1973, the dam stands at a hydraulic height of 20 feet and a length of 500 feet, with a storage capacity of 144 acre-feet. Situated on TR-Limestone Creek, the dam serves as a vital structure for water resource management in the area.

Despite being state-owned, State Cattle Ranch Dam No 6 is not regulated or inspected by any state agency, indicating a lack of formal oversight. The dam is primarily used for purposes other than flood control or irrigation, with a low hazard potential and a current condition assessment of "Not Rated." The dam's emergency action plan status, risk assessment, and management measures are not clearly defined, raising concerns about its resilience to potential climate-related challenges.

With its location in Hale County, Alabama, State Cattle Ranch Dam No 6 presents an intriguing case study for water resource and climate enthusiasts. The dam's history, design, and operational status offer insights into the complexities of managing and maintaining critical infrastructure in the face of evolving environmental conditions. Further research and monitoring may be necessary to ensure the dam's long-term safety and effectiveness in the context of changing climate patterns.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
