Summary
This earth dam, primarily used for recreation purposes, has a storage capacity of 120 acre-feet and serves as a water supply source. The dam is situated on the TR-Hondo Creek and is regulated by the state with regular inspections to ensure its structural integrity.
Despite not having a spillway, Geo Wilson Lake No 2 Dam poses a high risk due to its condition assessment being not rated. The dam's hazard potential is not available, and it lacks emergency action plans and inundation maps. Owned privately, this dam has one outlet gate and is not under the jurisdiction of any federal agency. Although it does not have a designated state regulatory agency, it is subject to state permitting and inspection requirements.
Water resource and climate enthusiasts may find Geo Wilson Lake No 2 Dam intriguing due to its unique design as an earth dam with buttress core types. The dam's location on the TR-Hondo Creek offers opportunities for recreational activities, while also fulfilling water supply needs. With its history dating back to the 1960s, this dam serves as a testament to the importance of water resource management and infrastructure development in Texas.

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.
