Dam 11 Reservoir Report
Nearby: Ft. Hood Site 35b-1 Dam 12
Last Updated: March 3, 2026
Dam 11, also known as 45g, is a federal-owned recreational dam located in Copperas Cove, Texas.
Summary
Managed by the US Army, this earth dam with a buttress core stands at a height of 25 feet and stretches 540 feet in length. It serves a primary purpose of recreation and has a storage capacity of 83 acre-feet, with a normal storage level of 36 acre-feet.
Despite its low hazard potential, Dam 11 has a moderate risk assessment rating of 3 due to its location on the Coryell River. The dam features an uncontrolled spillway with a width of 30 feet and has a surface area of 2 acres. While the dam is not regulated by the state, it is subject to inspection every four years, with the last inspection conducted in September 2020.
Water resource and climate enthusiasts will find Dam 11 to be an intriguing structure that showcases the intersection of water management and recreational activities. With its unique design and location in Coryell County, Texas, this dam provides insights into the importance of responsible dam operation and maintenance in ensuring public safety and environmental protection.

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.
