Summary

Built in 1956 by the US Army, this earth dam stands at 18 feet tall and spans 680 feet in length, with a primary purpose of water supply. Managed by the US Army, Dam 43 has a maximum storage capacity of 58 acre-feet and a normal storage capacity of 19 acre-feet, serving the surrounding area with water from Tr House Creek.

Despite its low hazard potential, Dam 43 has a moderate risk assessment rating and undergoes inspections every four years, with the last inspection conducted in September 2020. The dam features an uncontrolled spillway with a width of 20 feet, and its associated structures include rock and soil foundations. While the condition assessment is currently not available, the emergency action plan was last revised in May 2010, indicating a commitment to safety and preparedness in the event of any unforeseen incidents. Dam 43 remains a vital water resource infrastructure in Coryell County, Texas, contributing to the region's water supply needs.

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.
