Summary
Completed in 1977, this buttress-style dam stands at a height of 25 feet and has a storage capacity of 174 acre-feet. With a surface area of 13 acres and a drainage area of 120 acres, the dam plays a crucial role in managing water resources in the area.
Despite its recreational significance, Lewis Lake North Dam poses a high hazard potential due to its condition being not rated. The dam has not been inspected recently, and there is no emergency action plan in place. These factors raise concerns about the safety and management of the dam, especially in the face of potential climate-related challenges such as increased precipitation and extreme weather events.
As water resource and climate enthusiasts, it is essential to monitor and address the condition of dams like Lewis Lake North Dam to ensure sustainable water management practices and mitigate risks associated with climate change. By advocating for regular inspections, emergency preparedness, and risk assessment measures, we can help safeguard our water resources and communities against the impacts of a changing climate.

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.
