Summary
This private-owned Earth dam stands at a height of 30 feet, with a hydraulic height of 29 feet and a structural height of 31 feet. With a normal storage capacity of 30 acre-feet and a drainage area of 165 square miles, the dam plays a vital role in managing water resources in the region.
The dam's low hazard potential and moderate risk assessment indicate that it is well-maintained and poses minimal threat to surrounding areas. Although it is not regulated by the state and has not been inspected recently, the dam continues to fulfill its primary purpose of grade stabilization effectively. Despite its uncontrolled spillway type, the dam's design with a stone core and soil foundation ensures stability and reliability in managing water flow in the area.
Water resource and climate enthusiasts will appreciate the significance of Soendker Lake Dam in maintaining the ecological balance and safeguarding the surrounding community from potential flooding. As a key structure in the region, the dam's role in managing water storage and flow highlights the importance of sustainable infrastructure in adapting to climate change and ensuring water security for future generations.

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.
