Summary
This earth dam stands at a height of 28 feet with a structural height of 30 feet and a length of 550 feet, providing a maximum storage capacity of 342 acre-feet. The dam's low hazard potential and moderate risk assessment make it a crucial structure for managing water resources in the area.
Managed by the local government, this dam plays a key role in protecting the surrounding Lewis County from potential flooding events. With a drainage area of 12.8 square miles and a maximum discharge capacity of 860 cubic feet per second, Durgens Creek Watershed Dam 4 serves as a vital line of defense against excess water flow during heavy rainfall or snowmelt. Despite not being state-regulated, the dam's design and construction by the Natural Resources Conservation Service ensure its reliability in flood risk reduction.
Water resource and climate enthusiasts will appreciate the significance of Durgens Creek Watershed Dam 4 in maintaining the safety and integrity of the surrounding area. With its stone core and soil foundation, this earth dam stands as a testament to effective water management strategies in the face of changing environmental conditions. Its uncontrolled spillway and lack of outlet gates highlight the simplicity and efficiency of its design, making it a valuable asset for flood risk reduction efforts in the region.

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.
