Summary
Built in 1999 by the NRCS, this earth dam stands at 42 feet high and spans 900 feet in length. Its primary purpose is debris control, providing a critical function in managing water resources in the area. The dam has a capacity of 402 acre-feet of storage and a surface area of 10 acres, serving as a key component in flood control and water management efforts in the region.
Managed and funded by the US Army, Dam 31 has a low hazard potential and is categorized as having a moderate risk level. Despite this, its condition assessment is currently not available, highlighting the need for ongoing monitoring and maintenance. The dam features an uncontrolled spillway with a width of 70 feet, ensuring effective water discharge during peak flow events. With its last inspection conducted in September 2020, Dam 31 is a crucial infrastructure asset that plays a vital role in safeguarding the local community and environment from potential water-related hazards.
As a key component of the water management system in Coryell County, Dam 31 serves as a critical infrastructure for debris control along House Creek. With its strategic location and design, the dam provides essential flood protection and water storage capacity, contributing to the overall resilience of the region. Moving forward, continued monitoring and maintenance of Dam 31 will be essential to ensure its long-term functionality and effectiveness in mitigating water resource challenges in the area.

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.
