Summary
This earth dam, designed by USDA NRCS, stands at a height of 41 feet and spans 3400 feet, providing a maximum storage capacity of 5318 acre-feet. The dam's fair condition assessment in 2015 and moderate risk assessment highlight its importance in protecting the surrounding area from potential flooding events.
Managed by the local government and regulated by the Texas Commission on Environmental Quality (TCEQ), Plum Creek WS SCS Site 21 Dam is equipped with an uncontrolled spillway and multiple outlet gates for water release. With a drainage area of 8.65 square miles and a surface area of 56.95 acres, the dam plays a crucial role in managing water flow and minimizing flood risks in the region. Despite its age, the dam continues to undergo regular inspections and maintenance to ensure its continued effectiveness in flood risk reduction.
In the event of an emergency, the dam's emergency action plan (EAP) status and risk management measures are not specified, indicating a potential area for improvement. However, with its significant storage capacity and design features, Plum Creek WS SCS Site 21 Dam remains a vital infrastructure asset for the community, providing essential protection against flooding and safeguarding water resources in the area.

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.
