Summary

Built by PARKHILL SMITH & COOPER in 1950, this Earth dam stands at a height of 42.6 feet and has a storage capacity of 2150 acre-feet to serve the surrounding area's water needs. The dam is situated on Mountain Creek and is regulated by the Texas Commission on Environmental Quality (TCEQ).

With a fair condition assessment and a moderate hazard potential, Mountain Creek Dam features an uncontrolled spillway and a combination of uncontrolled and valve outlet gates. The dam has a drainage area of 32 square miles and a maximum discharge capacity of 77,792 cubic feet per second. Despite its age, the dam undergoes regular inspections with a frequency of every 5 years to ensure its structural integrity and safety for the community it serves. Water resource and climate enthusiasts will appreciate the combination of historical significance and functional importance that Mountain Creek Dam holds in the region.

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.
