Summary
Built in 1968, the dam stands at a height of 16 feet and spans a length of 600 feet, with a storage capacity of 180 acre-feet. Despite its modest size, the dam plays a crucial role in providing water to the surrounding area, ensuring a stable water supply for local communities and ecosystems.
The dam's design features buttress core types and is situated on TR-Pertle Creek, managed by the Fort Worth District. While the dam lacks a spillway and has not been rated for condition assessment, it is classified as having a high risk potential. With no state jurisdiction or enforcement, the dam's inspection and maintenance fall under the responsibility of the private owner. As climate change continues to impact water resources, monitoring and managing infrastructure like Robert Wheeler Lake No 2 Dam becomes increasingly important for water resource and climate enthusiasts.
Overall, Robert Wheeler Lake No 2 Dam serves as a vital water source in Texas, highlighting the intersection of water resource management, infrastructure maintenance, and climate resilience. As enthusiasts in these fields continue to advocate for sustainable water practices and climate adaptation strategies, the dam's role in ensuring water security and mitigating risks underscores the importance of proactive management and investment in resilient infrastructure. With ongoing challenges posed by climate change, the case of Robert Wheeler Lake No 2 Dam exemplifies the need for robust systems and policies to safeguard water resources for future generations.

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.
