Summary
Built in 1973 by the USDA NRCS, this structure serves primarily for flood risk reduction along the Comanche Creek. Standing at 46 feet high with a length of 495 feet, the dam has a storage capacity of 217 acre-feet and covers a surface area of 17 acres.
With a low hazard potential and a satisfactory condition assessment, Triple L Det #1 has proven to be a reliable asset for managing water resources in the region. The dam features an uncontrolled spillway that is 150 feet wide and can handle a maximum discharge of 3700 cubic feet per second. Inspected every three years, the structure is regulated, permitted, and enforced by the Colorado Department of Water Resources, ensuring its safety and functionality for the surrounding community.
Despite its moderate risk assessment, Triple L Det #1 remains a vital component in the local water infrastructure, providing essential flood protection and storage capabilities. As water resource and climate enthusiasts, understanding the design, purpose, and maintenance of structures like Triple L Det #1 is crucial for ensuring sustainable water management practices in the face of changing environmental conditions.

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.
