Summary
The dam, standing at 40 feet high and stretching 1000 feet in length, holds a storage capacity of 458 acre-feet and serves as a vital component in managing the water resources of the Mill Creek tributary. With a surface area of 20 acres and a drainage area of 318 square miles, the dam plays a crucial role in flood control and water supply for the region.
Despite its high hazard potential, White Lake Dam has been assessed as satisfactory and meets regulatory guidelines for safety and maintenance. The dam features an uncontrolled spillway with a width of 110 feet and outlet gates for water release. Regular inspections, conducted every 2 years, ensure the structural integrity of the dam and its ability to withstand potential emergencies. With a moderate risk assessment score of 3, the dam is equipped with management measures to mitigate any potential risks and ensure the safety of the surrounding community and environment. Water resource and climate enthusiasts can appreciate the engineering and regulatory efforts put into maintaining this essential infrastructure for both recreational and water management purposes.

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.
