Summary

This earth dam on the TR-COLORADO RIVER stands at a height of 24 feet and has a maximum storage capacity of 36 acre-feet, with a normal storage of 19 acre-feet. It covers a surface area of 1.93 acres and has a drainage area of 0.24 square miles.

The dam, which was last inspected in May 2015 and assessed to be in fair condition in February 2016, features an uncontrolled spillway with a width of 68 feet. It has two uncontrolled outlet gates and a moderate hazard potential. The risk assessment for Moore Dam is categorized as a level 3, indicating moderate risk. The dam has been modified in 2014 for hydraulic purposes, and it is under the regulatory jurisdiction of the Texas Commission on Environmental Quality (TCEQ).

Overall, Moore Dam plays a crucial role in irrigation and water supply in the region, contributing to the management of water resources in Travis County. With its strategic location on the Colorado River and its functional design, the dam serves as an essential infrastructure for sustainable water usage and agricultural activities in the area.

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.
