Summary

Completed in 1986, this concrete dam stands at a height of 30 feet and serves primarily for irrigation purposes, with a storage capacity of 400 acre-feet. The dam is situated on Smithfield Creek and has a surface area of 20.5 acres, with a drainage area of 6.7 square miles.

Despite its age, Stoneglen Dam No 1 has not been rated for its condition and its hazard potential is listed as "Not Available." However, a risk assessment categorizes the dam as having a high risk level (2). The dam does not have a spillway and is equipped with one outlet gate. The dam is regulated by the Texas Commission on Environmental Quality (TCEQ) and undergoes state inspection, permitting, and enforcement.

With its significant role in irrigation and potential risks identified, Stoneglen Dam No 1 stands as a crucial structure in water resource management in the region. Its design and construction by HALFF AND ASSOCIATES INC showcase expertise in engineering, and ongoing regulatory oversight by TCEQ ensures the safety and functionality of the dam for both its intended purposes and the surrounding environment.

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.
