Summary
Managed by the local government, the dam stands at 37 feet in height and spans 3090 feet in length, with a storage capacity of 10,032 acre-feet. Situated on Elm Creek, the dam is regulated by the Texas Commission on Environmental Quality (TCEQ) and undergoes regular inspections and enforcement measures to ensure its safety and functionality.
Constructed by French Engineering Co, Old Lake Winters City Dam is classified as an earth dam with a buttress core foundation. Equipped with an uncontrolled spillway and 4 uncontrolled and 1 valve outlet gates, the dam is designed to handle maximum discharges and maintain water levels in the reservoir. With a moderate risk assessment rating, the dam's hazard potential is not available, and its condition is yet to be rated. While the dam's Emergency Action Plan (EAP) status and readiness for potential emergencies are unspecified, the local government continues to monitor and manage the dam to safeguard water resources and public safety in the area.
As a key infrastructure for water resource management in Runnels County, Texas, Old Lake Winters City Dam plays a crucial role in supplying water for various purposes. With its strategic location and design features, the dam stands as a testament to engineering excellence and serves as a vital asset for the community. As climate change impacts water availability and quality, the dam's maintenance and regulatory oversight are essential to ensuring a sustainable water supply for the region for years to come.

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.
