Summary
This structure, designed by ROADWAY RETENTION, serves as a buttress dam with a height of 31 feet and a storage capacity of 920 acre-feet. The dam was completed in an unlisted year and spans 1940 feet across Threemile Creek, with a drainage area of 27.6 square miles.
With a low hazard potential and a condition assessment of "Not Rated," Island Lake 13 & 24 is a key component of the water management infrastructure in the region. While the dam does not currently have a designated primary purpose or specified purposes, it plays a critical role in flood control, water supply, and ecosystem management. Regular inspections are conducted every 8 years to ensure the safety and functionality of the structure, with emergency action plans and risk management measures in place to address any potential issues that may arise. For water resource and climate enthusiasts, Island Lake 13 & 24 offers a fascinating glimpse into the intersection of human engineering and natural resource management in a dynamic and ever-changing environment.

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.
