Summary

Constructed in 1961 by C L MOON INC, this private-owned Earth dam stands at a height of 33 feet and has a capacity to hold up to 1000 acre-feet of water from the TR-COON CREEK. The dam's spillway is uncontrolled with a width of 175 feet, and it has undergone structural modifications in 1977.

Despite being in moderate risk category with a hazard potential that is not available, Gator Lake Dam is equipped with four uncontrolled outlet gates and has not been rated for its condition assessment. The dam, managed by the Texas Commission on Environmental Quality (TCEQ), has a maximum discharge capacity of 18,400 cubic feet per second and a normal storage level of 940 acre-feet. With the last inspection conducted in 1983, the dam's risk management measures and emergency preparedness plans are not currently available.

Overall, Gator Lake Dam stands as a significant water resource structure in the region, contributing to agricultural irrigation and recreational activities while being subject to state regulation and inspection. Its history of construction and modifications, along with its capacity and location in Anderson, Texas, make it an intriguing site for water resource and climate enthusiasts to study and appreciate.

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.
