Summary

Completed in 1996, this earth dam stands at a height of 16 feet and spans a length of 1400 feet, providing a maximum storage capacity of 204 acre-feet. Despite its relatively small size, the dam plays a significant role in managing water flow and storage in the area, contributing to the overall water management efforts in the region.

Managed and regulated by the Texas Commission on Environmental Quality (TCEQ), Yett Creek Park Dam has been inspected regularly, with the most recent assessment in 2014 rating its condition as fair. The dam's spillway, with a width of 111 feet, is designed as uncontrolled, allowing for controlled release of excess water during periods of high flow. With a moderate risk assessment score of 3, the dam is considered to have a manageable level of potential hazards, highlighting the importance of ongoing maintenance and monitoring to ensure its continued effectiveness in water management and flood control.

For water resource and climate enthusiasts, Yett Creek Park Dam serves as a prime example of localized water management infrastructure that plays a critical role in maintaining the ecological balance and water supply in the region. With its modest but essential capabilities, the dam stands as a testament to the careful planning and execution required for sustainable water resource management in a changing climate landscape.

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.
