Summary
Standing at a height of 24.2 feet with a hydraulic height of 23.4 feet, this dam has a storage capacity of 362 acre-feet, with a normal storage level of 216 acre-feet. The dam spans 750 feet in length and covers a surface area of 24 acres, providing a serene setting for outdoor activities.
Despite its low hazard potential, Isler Lake Dam has a moderate risk assessment rating of 3, highlighting the importance of regular inspections and maintenance. While the dam's condition is currently not rated, it has been inspected as recently as June 2019 with a scheduled inspection frequency of every 5 years. The dam features uncontrolled spillways and outlet gates, posing a potential risk that necessitates ongoing risk management measures and emergency preparedness.
Water resource and climate enthusiasts will appreciate the unique design and purpose of Isler Lake Dam, as well as the need for continued monitoring to ensure its safety and functionality. As a key recreational feature in the area, this dam serves as a vital resource for the local community while also requiring careful attention to mitigate any potential risks associated with its operation.

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.
