Summary
Completed in 1974, this earth dam, with a height of 10 feet and a length of 900 feet, serves as a vital structure for regulating the flow of the TR-Rio Grande river. With a storage capacity of 64 acre-feet, the dam plays a crucial role in water management and flood control in the area.
Despite being privately owned, the Carter Lake No 1 Dam is subject to state permitting and inspection, ensuring its structural integrity and safety. While the dam does not have a spillway, it is equipped with an outlet gate to manage water levels effectively. The risk assessment for this dam is classified as high, emphasizing the importance of proper maintenance and monitoring to prevent any potential hazards.
For water resource and climate enthusiasts, Carter Lake No 1 Dam offers a fascinating glimpse into the intersection of engineering, environmental stewardship, and water management. As a key infrastructure for the region, this dam serves as a reminder of the importance of sustainable practices in preserving our 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.
