With a low hazard potential and a moderate risk assessment rating, Durgens Creek Watershed Dam 1b is not currently regulated or inspected by the state, although it is owned by the local government. The dam, constructed with a stone core and soil foundation, serves as a vital infrastructure for managing water resources in the area and protecting downstream communities from potential flooding events. Its location within the Lewis County watershed contributes to the overall conservation efforts in the region, highlighting the importance of sustainable water management practices in mitigating climate-related risks.
