Summary

With a height of 25 feet and a length of 2085 feet, the dam serves multiple purposes including irrigation and flood control. It has a storage capacity of 1560 acre-feet and covers a surface area of 276 acres, making it a crucial water resource in the area.

Managed by the Texas Commission on Environmental Quality (TCEQ), Coyote Lake Dam is regulated, inspected, and enforced to ensure its structural integrity and safety. While it currently has a high risk assessment level, there are no spillways or locks associated with the dam. The condition assessment of the dam is currently not rated, highlighting the need for further evaluation and maintenance to mitigate potential hazards.

Despite its potential risks, Coyote Lake Dam plays a vital role in water management in the region, supporting agricultural activities and providing essential water resources. As climate change continues to impact water availability, the maintenance and regulation of dams like Coyote Lake Dam are crucial for ensuring the sustainability and resilience of water systems in Texas.

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.
