Truett, also known as Woodridge Lake, is a private water resource located in Shingletown, California. This dam on Ash Creek was completed in 1958 and serves multiple purposes such as irrigation, recreation, and water supply. Managed by the Natural Resources Conservation Service, Truett stands at 31 feet in height with a storage capacity of 219 acre-feet, covering a surface area of 24 acres.

Despite its age, Truett's condition assessment remains satisfactory, with the last inspection in November 2020 revealing no significant concerns. However, the dam is classified as having a high hazard potential, indicating the potential risks associated with its operation. The dam's emergency action plan was last revised in 2015, and while it meets guidelines, there is room for improvement in terms of risk management measures and inundation mapping to ensure the safety of downstream communities.

With its vital role in water supply and recreational activities, Truett serves as a crucial infrastructure in the region. Water resource and climate enthusiasts can appreciate the careful regulation and maintenance of such dams to ensure their continued functionality and safety in the face of changing environmental conditions. As the state of California experiences ongoing water challenges, the importance of maintaining and monitoring dams like Truett becomes increasingly evident in securing water resources for the future.
