Summary
Completed in 1966, the earth dam stands at a height of 28.8 feet and has a storage capacity of 26.7 acre-feet, making it a vital water resource in the region. The dam sits on a tributary to Rainbow Creek and is regulated by the Department of Natural Resources, ensuring its safety and compliance with state standards.
Despite its low hazard potential and fair condition assessment, Strahler's Lake Dam is subject to regular inspections every five years, with the last assessment conducted in November 2018. The dam's maintenance and emergency preparedness are crucial for safeguarding the surrounding area from potential risks. With a maximum discharge capacity of 325 cubic feet per second, the dam plays a pivotal role in managing water levels and ensuring the safety of the community. For water resource and climate enthusiasts, Strahler's Lake Dam serves as a noteworthy example of sustainable infrastructure that balances recreational benefits with environmental responsibility in the face of changing climate 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.
