Summary
Completed in 1963, this earth dam stands at a height of 34 feet and spans a length of 3700 feet, with a storage capacity of 5447 acre-feet. With a fair condition assessment as of August 2015, the dam serves to protect the surrounding area from potential flooding events, with a maximum discharge capability of 12308 cubic feet per second.
Owned by the local government and regulated by the TCEQ, the Lower Plum Creek WS SCS Site 28 Dam is equipped with an uncontrolled spillway and multiple outlet gates for water flow control. With a moderate risk assessment rating, the dam is inspected every five years to ensure its structural integrity and overall functionality. Although the hazard potential is not available, the dam's presence plays a crucial role in managing water resources and climate-related challenges in the region, demonstrating the importance of proper infrastructure for flood mitigation and water management efforts.
In the event of an emergency, the dam's Emergency Action Plan (EAP) status and risk management measures are not specified, highlighting the need for continued vigilance and preparedness. As a key component in the local water infrastructure network, the Lower Plum Creek WS SCS Site 28 Dam underscores the importance of proactive risk assessment and maintenance practices in safeguarding communities from potential water-related disasters. For water resource and climate enthusiasts, this dam serves as a focal point for understanding the intersection of infrastructure, environmental stewardship, and resilience in the face of changing climatic 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.
