Summary
The primary purpose of this earth dam is debris control, with a height of 22 feet and a length of 1110 feet. It has a storage capacity of 272 acre-feet and a maximum discharge rate of 1542 cubic feet per second. The dam is owned, funded, designed, constructed, regulated, inspected, and operated by the US Army, highlighting its importance in national defense and infrastructure management.
Despite being classified as having a low hazard potential, Dam 21 is subject to moderate risk, with a risk assessment rating of 3. Regular inspections are conducted, with the most recent one taking place in September 2020. The dam does not fall under state regulation or permitting, further emphasizing its federal ownership and management. While the condition assessment is listed as "Not Available," the structure's overall risk management measures and emergency action plan status are not disclosed in the data.
For water resource and climate enthusiasts, Dam 21 serves as a crucial piece of infrastructure for debris control along the Coryell River in Texas. Its federal ownership and management by the US Army highlight its significance in national defense and emergency response efforts. With a moderate risk rating and regular inspections, the dam plays a vital role in ensuring the safety and stability of the surrounding area. Further details on its condition assessment, risk management measures, and emergency action plan status would provide a more comprehensive understanding of the dam's role in water resource management and climate resilience.

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.
