Summary
The dam is an earth structure with a height of 7.3 meters and a hydraulic height of 6 meters. It has a storage capacity of 3.6 million cubic meters and a length of 314 meters. The dam is under state regulation and inspection by the Alaska Department of Natural Resources.
Despite being in operation for over four decades, Roycroft Lake's condition assessment is currently listed as "Not Rated." The dam poses a significant hazard potential, although specific risk management measures and assessments are not detailed in the available data. Emergency action plans have been prepared and revised in the past, with the last revision dating back to 2003. The dam is not under the jurisdiction of the US Army Corps of Engineers.
Water resource and climate enthusiasts interested in the infrastructure and management of hydroelectric facilities may find Roycroft Lake intriguing. The dam's location in the Kenai Peninsula, Alaska, offers a unique perspective on the intersection of water resources, energy generation, and environmental stewardship in a remote and ecologically diverse region. Further exploration into the dam's risk assessment, emergency preparedness measures, and long-term sustainability plans could provide valuable insights into the challenges and opportunities of managing water resources in 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.
