Summary
The dam, primarily constructed of earth with a buttress core, stands at a height of 25 feet and spans 2800 feet in length. With a storage capacity of 1823 acre-feet and a drainage area of 3.51 square miles, this dam plays a crucial role in managing water flow and protecting the surrounding area from potential flooding.
Managed by the Texas Commission on Environmental Quality (TCEQ) and subject to state regulation, inspection, and enforcement, the dam has been assessed as satisfactory and deemed to have a moderate risk level. Equipped with a spillway and outlet gates for controlled water release, the dam has demonstrated effective functionality in reducing flood hazards. The surrounding community benefits from the dam's presence, ensuring the safety and security of residents in the event of heavy rainfall or increased water levels.
As water resource and climate enthusiasts, understanding the infrastructure and maintenance of dams like the Lower Plum Creek WS SCS Site 31 Dam is essential for promoting sustainable water management practices. By recognizing the vital role of such structures in mitigating flood risks and safeguarding communities, we can work towards a more resilient and water-secure future in the face of changing environmental conditions.

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.
