Summary
This earth dam stands at a height of 36 feet and has a length of 3340 feet, with a storage capacity of 5663 acre-feet. The dam's primary purpose is flood risk reduction, with a spillway width of 358 feet and a maximum discharge capacity of 25,641 cubic feet per second.
Managed by the local government and regulated by the Texas Commission on Environmental Quality (TCEQ), Plum Creek WS SCS Site 6 Dam has been deemed to be in satisfactory condition as of April 2021. Despite being uncontrolled, the dam features two uncontrolled outlets and one valve for controlled water release. Its risk assessment is moderate, with no specific hazard potential identified. The dam's location in Uhland, Texas, highlights its importance in protecting the surrounding area from potential flooding events, showcasing the collaboration between federal and state agencies in ensuring the safety of the community and the environment.
With its robust design, satisfactory condition, and strategic location, Plum Creek WS SCS Site 6 Dam stands as a vital infrastructure for flood risk management in Hays County. As water resource and climate enthusiasts, understanding the intricacies of this dam's construction, operation, and regulatory oversight sheds light on the collaborative efforts needed to mitigate flood risks and protect communities in vulnerable areas like Porter Creek. The dam's role in managing water flow and safeguarding against potential disasters underscores the critical importance of investing in sustainable water resource management practices for a resilient and climate-resilient future.

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.
