Bell Canyon, located in Napa, California, is a vital water resource managed by the local government for water supply purposes. The dam, completed in 1959 and standing at 95 feet tall with a storage capacity of 2530 acre-feet, harnesses water from Bell Creek to serve the community of St Helena. The reservoir covers an area of 76 acres and has a drainage area of 5.53 square miles, providing a critical source of water for the region.

Despite its age, Bell Canyon Dam is in satisfactory condition and regularly inspected by the California Department of Water Resources for safety and regulatory compliance. With a high hazard potential due to its location and size, the dam has established emergency action plans and contacts to ensure preparedness in case of any unforeseen events. The dam's spillway type, width, and other details are not specified in the data, but its importance as a water supply infrastructure underscores the need for continued monitoring and maintenance to ensure the safety and reliability of the reservoir for the surrounding community. Bell Canyon serves as a testament to the enduring importance of water resource management and infrastructure in the face of climate challenges.
