Summary
This earth dam stands at 32 feet high and spans 1100 feet in length, with a storage capacity of 3123 acre-feet and a drainage area of 10.5 square miles. The dam features an uncontrolled spillway and a combination of slide and uncontrolled outlet gates.
Despite being classified as having a fair condition assessment as of April 2021, the dam's hazard potential and risk assessment are deemed moderate. The regulatory oversight and enforcement of the dam fall under the Texas Commission on Environmental Quality (TCEQ), with state permitting, inspection, and enforcement in place. While the dam has not undergone recent modifications or emergency action plan updates, it continues to serve its primary purpose of flood risk reduction in the region, under the ownership of the local government.
In the event of an emergency, the dam's emergency action plan (EAP) status is unclear, but the dam is equipped with measures to manage risks. With its strategic location and vital role in protecting the surrounding area from flooding, Turkey Creek WS SCS Site 6 Dam stands as a significant water resource infrastructure in Callahan County, Texas, attracting the attention of water resource and climate enthusiasts alike.

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.
