Summary
Built in 1964, this earth dam stands at a height of 20 feet and has a storage capacity of 1144 acre-feet, with a normal storage capacity of 572 acre-feet. The dam spans 1250 feet in length and has a spillway width of 260 feet, making it a significant structure for managing water resources in the area.
Although the dam has not been rated for its condition assessment, it is under state jurisdiction and regulation by the Texas Commission on Environmental Quality (TCEQ). With three uncontrolled outlet gates, it is designed to manage the flow of water from Connally Creek, providing essential support for agricultural activities in the region. While the hazard potential is not available, the risk assessment for the dam is moderate, indicating the need for ongoing monitoring and maintenance to ensure its safety and efficiency in water management.
Overall, Connally Lake No 2 Dam stands as a vital infrastructure for water resource management in Wilson County, Texas. With its primary purpose of irrigation and water supply, the dam plays a critical role in supporting agricultural activities in the area. As climate enthusiasts and water resource advocates, understanding the importance and functionality of dams like Connally Lake No 2 is essential for promoting sustainable water management practices and ensuring the resilience of water resources in the face of changing climate conditions.

Condition Assessment
SatisfactoryNo 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
HighDams 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.
