Summary

Designed by CH2MHILL and Freese and Nichols, this earth-type dam stands at a height of 87 feet and has a hydraulic height of 85.8 feet, providing a maximum storage capacity of 2880 acre-feet. Completed in 2012, this structure serves a primary purpose of water management for the Dry Comal Creek watershed, with a drainage area of 5.61 square miles.

With a structural height of 146 feet and a length of 1570 feet, Dry Comal Creek FRS 11 boasts a maximum discharge capacity of 34642 cubic feet per second, controlled by an uncontrolled spillway. The dam's condition assessment as of February 2015 was reported as satisfactory, with a moderate risk level of 3. Emergency action plans and risk management measures are not readily available for this structure, indicating a potential area for improvement in preparedness and response. Overall, Dry Comal Creek FRS 11 plays a crucial role in water management and flood control for the surrounding area, highlighting the importance of monitoring and maintaining infrastructure for water resource and climate enthusiasts.

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.
