Summary
This local government-owned reservoir was completed in 1957 and stands as a vital water supply source for the area, with a maximum storage capacity of 251 acre-feet and a normal storage of 171 acre-feet. The dam, primarily constructed of earth with stone core types, reaches a height of 33 feet and spans 578 feet in length, serving the purpose of water supply for the region.
Despite its low hazard potential and fair condition assessment, Mirror Lake #1 is subject to a high risk assessment level of 2, prompting the need for regular inspections and risk management measures. The reservoir, situated on Lake Canyon, lacks a spillway but is equipped with slide and uncontrolled outlet gates. With a drainage area of 1 square mile and a surface area of 16 acres, this water source plays a crucial role in maintaining the water supply for the surrounding community. Although its risk assessment is high, the local regulatory agencies ensure that the dam meets state permitting, inspection, and enforcement requirements to safeguard against potential risks.
In the enchanting landscape of Mirror Lake #1, water resource and climate enthusiasts can appreciate the harmonious blend of nature and infrastructure. With a striking backdrop of rock and soil foundations, this reservoir stands as a testament to responsible water management practices in Colorado. As water enthusiasts explore the beauty of this area, they can also reflect on the importance of sustainable water resource management in the face of changing climate patterns.

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.
