Summary
Standing at 25 feet in height with a length of 640 feet, this structure plays a vital role in managing water resources in the region. With a maximum storage capacity of 53 acre-feet and a normal storage of 35 acre-feet, Mock #1 serves a drainage area of 12 square miles and can discharge up to 480 cubic feet per second.
Despite its age, Mock #1 has been deemed to have a low hazard potential and fair condition as of the last assessment in 2017. The dam is not equipped with a spillway, but features slide and uncontrolled gates for outlet purposes. The risk assessment for this dam indicates a high risk level, urging the need for continuous monitoring and management measures to ensure its structural integrity and safety. With state regulation, inspection, and enforcement in place, Mock #1 remains a key component in the water resource infrastructure of the area, under the oversight of the Colorado Division of Water Resources.
As climate change continues to impact water availability and usage patterns, Mock #1 stands as a testament to the importance of proper dam maintenance and risk management in safeguarding water resources for irrigation and other purposes. Its location along the Uncompahgre River, within the Albuquerque District of the US Army Corps of Engineers, highlights the interconnectedness of water infrastructure across state and federal levels. With a focus on sustainable water management practices, Mock #1 serves as a critical asset for the community while facing the challenges of a changing climate landscape.

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.
