Summary
Built in 1930, this reservoir serves primarily as a Fish and Wildlife Pond, with additional recreational purposes. The dam stands at 11 feet in height, with a length of 1050 feet and a storage capacity of 161 acre-feet.
Situated on Jim Creek, Banner Lake #8 covers a surface area of 22 acres and has a drainage area of 6 square miles. The dam has an uncontrolled spillway with a width of 30 feet and a maximum discharge of 950 cubic feet per second. Despite being classified as having a low hazard potential, the dam's condition was last assessed as satisfactory in 2009.
Climate enthusiasts will appreciate this structure's moderate risk assessment and its role in supporting fish and wildlife in the area. With its historical significance dating back nearly a century, Banner Lake #8 remains a vital part of the local ecosystem and a focal point for conservation efforts in Colorado.

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.
