Summary

Completed in 1940, this dam serves the primary purpose of water supply, with a storage capacity of 73 acre-feet and a normal storage level of 43 acre-feet. The dam stands at 17 feet tall and stretches 130 feet in length, providing essential water resources for the surrounding area.

Situated on North East Creek-TR, King #2 is regulated and permitted by the Colorado Department of Water Resources (DWR). Despite being classified as low hazard potential with fair condition assessment, the dam poses a high risk due to its location and surrounding factors. With a maximum discharge capacity of 3800 cubic feet per second and no spillway, the dam's safety and maintenance are crucial for the community's water security.

Although last inspected in 2016, with a scheduled inspection frequency of 6 years, King #2's risk management measures and emergency preparedness remain unspecified. With a risk assessment rating of 2, enthusiasts and stakeholders in water resources and climate should monitor this dam closely to ensure its continued functionality and safety in the face of potential hazards.

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.
