Summary
This dam stands at a height of 13 feet, with a length of 760 feet and a storage capacity of 112 acre-feet. The dam, situated on Jim Creek, also serves recreational purposes and has a spillway width of 25 feet.
Despite being classified as having a low hazard potential, the dam's condition was assessed as fair during its last inspection in November 2017. With a moderate risk level, measures for risk management and emergency action planning were not explicitly stated in the data. The dam is regularly inspected every 6 years and falls under the jurisdiction of the Colorado Department of Water Resources, ensuring compliance with state regulations for permitting, inspection, and enforcement.
Water resource and climate enthusiasts can appreciate Banner Lake #5 for its role in supporting fish and wildlife habitats while offering recreational opportunities in the region. As a vital structure for water management and conservation, this dam serves as a testament to the importance of maintaining infrastructure for both ecological and recreational purposes in the face of changing environmental conditions.

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.
