Summary
Built in 1970, this Earth dam structure stands at 28 feet in height, with a length of 4855 feet, providing a storage capacity of 1781 acre-feet for recreational purposes like fishing and wildlife conservation. The reservoir is regulated by the Colorado Department of Water Resources, ensuring its proper inspection and enforcement to maintain its fair condition and low hazard potential.
Located on the White River, Johnnie Johnson offers a surface area of 149 acres and a maximum discharge of 8821 cubic feet per second. Despite its high-risk assessment due to its structural characteristics, its emergency action plan readiness and risk management measures are currently not available. With a scheduled inspection frequency of every 6 years, the reservoir remains a vital asset for water and climate enthusiasts, providing a scenic and recreational haven in the heart of Colorado's natural splendor.
Enthusiasts and conservationists can appreciate the significance of Johnnie Johnson as a crucial water resource in Colorado, not only serving as a recreational hub but also supporting fish and wildlife conservation efforts. As a state-regulated entity under the jurisdiction of the Colorado Department of Water Resources, the reservoir's environmental impact and safety are closely monitored. Its low hazard potential, fair condition, and high-risk assessment highlight the importance of ongoing inspection and risk management measures to ensure the longevity and sustainability of this valuable water source in the region.

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.
