Summary

This earth dam stands at a height of 81 feet and spans a length of 1157 feet, providing essential protection for the surrounding area along York Creek. With a storage capacity of 4570 acre-feet, the dam serves multiple purposes including flood risk reduction, grade stabilization, and water supply for the local community.

Managed by the TCEQ and regulated by the state of Texas, the dam boasts a spillway width of 292 feet and a maximum discharge of 72970 cubic feet per second. The dam's structure, primarily composed of stone core and supported by rock and soil foundations, has been inspected regularly with the last evaluation conducted in January 2016. Despite its moderate risk assessment rating, the York Creek WS SCS Site 1 Dam continues to play a crucial role in safeguarding the area against potential flooding events and ensuring water resource sustainability for the region.

With its strategic location and effective design, the York Creek WS SCS Site 1 Dam stands as a testament to the importance of sound water resource management and climate resilience efforts. As climate change continues to impact water availability and flood risks, the dam's critical role in flood risk reduction and water supply highlights the need for ongoing monitoring and maintenance to ensure the safety and sustainability of the surrounding community and ecosystem.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
