Lower Howell, also known as Lake Couzzens, is a public utility-owned dam located in Los Gatos, California. Built in 1877, this earth dam stands at a height of 39 feet and has a hydraulic height of 35.1 feet, with a storage capacity of 153 acre-feet. The dam serves the primary purpose of water supply, drawing water from Rundell Creek and covering a surface area of 8 acres.

Managed by the California Department of Water Resources and regulated for safety by the Safety of Dams program, Lower Howell has a significant hazard potential but is currently assessed as satisfactory in condition. The dam underwent its last inspection in September 2020, with a scheduled frequency of every 1 year. While there are no associated structures or spillways, the dam's drainage area is 0.16 square miles, indicating a modest but essential role in local water management.

With its historical significance dating back over a century, Lower Howell remains a vital component of the water infrastructure in Santa Clara County. Enthusiasts of water resources and climate resilience can appreciate the role this dam plays in providing water supply to the surrounding area, while also recognizing the ongoing efforts to ensure its safety and functionality for future generations.
