Summary
This earth dam, with a height of 39.5 feet and a length of 4308 feet, serves the primary purpose of mitigating flood risks along Gap Creek. Completed in 1998, it has a storage capacity of 6500 acre-feet and a normal storage level of 200 acre-feet, covering a surface area of 64 acres.
The dam, regulated by the Texas Commission on Environmental Quality (TCEQ), features an uncontrolled spillway with a width of 340 feet and two uncontrolled outlet gates. With a moderate risk assessment rating, it is inspected, permitted, and enforced by state agencies to ensure its structural integrity and functionality. While hazard potential information is not available, the dam's condition is currently unrated, highlighting the need for ongoing maintenance and assessments to uphold its flood protection role in the region.
Overall, Elm Creek WS NRCS Site 7 Rev stands as a critical infrastructure for flood risk reduction in the area, safeguarding communities and natural habitats from potential water-related disasters. As water resource and climate enthusiasts, the site's design, construction, and regulatory framework offer valuable insights into the interplay between human-built structures and natural water systems, emphasizing the importance of sustainable water management practices for a resilient future.

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.
