Summary
With a height of 10 feet and a length of 700 feet, this Earth dam on Jim Creek offers a serene setting for fish and wildlife ponds, as well as leisure activities. The dam has a storage capacity of 66 acre-feet, with a normal storage level of 42 acre-feet and a surface area of 13 acres.
Despite being classified as having a low hazard potential, Banner Lake #3 has a moderate risk level, indicating a need for ongoing monitoring and management. The last inspection dates back to 1997, with an inspection frequency of 6 years. While the condition of the dam is currently not rated, the regulatory agencies in Colorado are involved in permitting, inspection, and enforcement activities to ensure the safety and integrity of the structure. Climate and water resource enthusiasts can appreciate the balance between recreational use and responsible dam management at Banner Lake #3, making it a noteworthy site for conservation efforts and environmental awareness 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.
