Summary
The dam is classified as an Earth dam with a height of 21 feet and a length of 540 feet. It has a storage capacity of 50 acre-feet, with a normal storage level of 37 acre-feet.
Despite its importance for water supply, Stern Lake Dam has not been rated for its condition assessment and its hazard potential is marked as "Not Available." The dam does not have a spillway and is not regulated by the state. While the risk assessment is considered high, no specific risk management measures have been outlined for the dam.
As an enthusiast of water resources and climate, the data for Stern Lake Dam underscores the need for proper maintenance and assessment of our infrastructure to ensure the safety and efficiency of our water supply systems. The lack of a spillway and unclear condition assessment highlight potential areas of concern that should be addressed to mitigate risks and protect the surrounding community. Stay tuned for updates on the ongoing management and monitoring of Stern Lake Dam to ensure its continued functionality and safety.

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.
