In the heart of Napa, California, lies Conn Creek, also known as Lake Hennessey, a water supply reservoir built in 1946 and managed by the local government. This Earth-type dam stands at 125 feet high and has a storage capacity of 31,000 acre-feet, serving primarily for irrigation and water supply purposes. With a surface area of 790 acres and a drainage area of 54 square miles, Conn Creek plays a vital role in supporting the agricultural and residential needs of the region.

Despite its age, Conn Creek has undergone regular state inspections and enforcement to ensure its safety and functionality.

As a key component of the Sacramento District, Conn Creek highlights the importance of sustainable water resource management in the face of climate change challenges. Its strategic location, coupled with its historical significance and ongoing regulatory oversight, underscores the critical role that dams like Conn Creek play in preserving and enhancing water security for communities in California.
