Summary
The dam has a storage capacity of 185 acre-feet, with a normal storage level of 140 acre-feet and a surface area of 14 acres. Although the dam is uncontrolled in terms of spillway type and outlet gates, its hazard potential is rated as low, with a moderate risk assessment score of 3.
While the dam is not regulated by the state, it undergoes inspections every five years, with the last inspection conducted in May 2017. Despite being in good condition and not having a formal rating, the dam has not been modified or had its emergency action plan (EAP) updated recently. The risk management measures and inundation maps for the area have not been prepared or updated, but the dam is considered to have a moderate level of risk.
Overall, Sanders Lake Dam serves as a significant water resource in the region, providing storage for water and serving as a low-risk structure. However, there is a need for more regular inspections, updated emergency preparedness plans, and risk assessment measures to ensure the safety and security of the dam and surrounding areas in the face of potential climate challenges.

Dam Data Reference
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.
