Summary
Completed in 1967, this earthen dam stands at a height of 13 feet and spans a length of 1365 feet, with a storage capacity of 614 acre-feet. Situated on Comanche Creek, the dam serves as a vital resource for water management in the region, with a surface area of 118 acres and a drainage area of 4.7 square miles.
Despite its critical role in water resource management, Chimney Tank Dam does not have a spillway and is classified as having a high risk level. The dam is not rated for its condition assessment, and there is no information available on its emergency action plan or inundation maps. However, the dam is inspected, regulated, and permitted by the Texas Commission on Environmental Quality (TCEQ), ensuring its compliance with state regulations and enforcement measures.
As a key structure in the Fort Worth District, Chimney Tank Dam plays a crucial role in providing water for various purposes while also posing potential risks that need to be managed effectively. Its presence on Comanche Creek adds to the water resource infrastructure in the area, highlighting the importance of proper maintenance and monitoring to ensure safe and sustainable water management practices for the community and the environment.

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.
