Summary
This earth dam with a buttress core serves a primary purpose that falls under the "Other" category, and has a storage capacity of 301 acre-feet. The dam is situated on the TR-RIO GRANDE river, within the jurisdiction of the state of Texas.
Despite being privately owned and not regulated by the state, Carter Lake No 2 Dam poses a high risk due to its hazard potential and the lack of a condition assessment rating. With no spillway and limited emergency preparedness measures in place, the dam's risk management measures and adherence to safety guidelines remain unclear. The absence of inspection and maintenance data further highlights the need for increased monitoring and oversight to ensure the structural integrity and safety of this important water resource.
For water resource and climate enthusiasts, Carter Lake No 2 Dam presents an intriguing case study in dam safety and risk management. With its location in a high-risk area and limited regulatory oversight, the dam serves as a reminder of the need for robust emergency preparedness measures and regular inspections to mitigate potential hazards and safeguard the surrounding community and environment. As climate change continues to impact water resources, the importance of maintaining and monitoring critical infrastructure like Carter Lake No 2 Dam becomes increasingly vital in ensuring long-term water security and resilience.

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.
