Summary
Completed in 1958, this earth dam reaches a height of 12 feet and spans a length of 800 feet, with a storage capacity of 115 acre-feet. Despite its modest size, the dam's risk assessment is classified as high, indicating potential hazards that warrant attention and monitoring.
Operated by a private entity, the dam lacks federal regulation and oversight, with the state permitting and inspection processes in place. While the spillway type is listed as 'None', the dam features one outlet gate for controlled water release. The condition of the dam is currently unrated, highlighting the need for further assessment and risk management measures to ensure its structural integrity and safety in the face of changing climate patterns and water resource demands.
For water resource and climate enthusiasts, the Prior Lake No 2 Dam presents an intriguing case study of a privately owned recreational dam in Texas. With its historical significance dating back to the late 1950s, this structure serves as a vital component of the local landscape, offering both leisure activities and potential risks associated with its high hazard rating. As discussions on water management and climate resilience continue to evolve, the Prior Lake No 2 Dam serves as a reminder of the complex interplay between human infrastructure, natural resources, and environmental sustainability.

Dam Data Reference
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.
