Summary
The dam, designed by Aaron Cook, stands at a height of 27.3 feet and has a hydraulic height of 24 feet. It spans 255 feet in length and has a storage capacity of 145 acre-feet, with a normal storage level of 83 acre-feet. The dam is situated on Guthrie Creek and is categorized as an earth dam with a buttress core foundation.
Despite being classified as having a low hazard potential, Janes Lake Dam has a moderate risk assessment rating of 3. The dam is inspected every five years, with the last inspection conducted in October 2017. While the condition assessment is marked as "Not Rated," the dam is not regulated by the state and does not require permitting or enforcement. In the event of an emergency, Janes Lake Dam currently does not have an Emergency Action Plan (EAP) in place. Overall, this dam serves as a recreational resource in the area, but its risk assessment highlights the importance of ongoing monitoring and maintenance to ensure the safety of surrounding communities and the environment.

Dam Data Reference
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.
