Summary

2 is a gravity dam located in Jefferson County, Colorado, with a primary purpose of water supply. Completed in 2008 by W.W. Wheeler and Associates, Inc., this impressive structure stands at a height of 103 feet and has a storage capacity of 127 acre-feet. The dam's spillway type is uncontrolled with a width of 224 feet, allowing for a maximum discharge of 4993 cubic feet per second.

Owned by a public utility and regulated by the Colorado Department of Water Resources, Genesee No. 2 is inspected regularly to ensure its satisfactory condition. Despite its high hazard potential, the risk assessment deems it moderate with appropriate risk management measures in place. The dam's location in a rock foundation contributes to its stability, while its multi-arch core design adds to its structural integrity.

Water resource and climate enthusiasts will appreciate the technical details of Genesee No. 2, including its unique features such as a roller-compacted concrete dam type and a surface area of 3 acres. With its strategic location and significant storage capacity, this dam plays a crucial role in providing water supply to the surrounding area, showcasing the importance of effective infrastructure in managing water resources in a changing climate.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
