Coyote Percolation is a vital water resource infrastructure located in San Jose, California, along the Coyote Creek. Built in 1934, this buttress dam stands at a height of 24 feet and has a storage capacity of 72 acre-feet, serving primarily for irrigation and water supply purposes. With a satisfactory condition assessment and high hazard potential, Coyote Percolation is under state regulation and inspection to ensure its safety and functionality.

Managed by a public utility, this dam plays a crucial role in water management for the Santa Clara County region. Its location within the Sacramento District and close proximity to urban areas like San Jose highlight the importance of balancing water supply needs with environmental sustainability. The dam's last inspection in April 2020 revealed its satisfactory condition, but ongoing monitoring and maintenance are essential to mitigate potential risks and ensure the safety of surrounding communities.

With a history dating back to the early 20th century, Coyote Percolation continues to be a key component of the local water infrastructure. As climate change impacts water resources and availability, the importance of maintaining and upgrading dams like Coyote Percolation to meet evolving needs and standards becomes increasingly crucial. As a strategic water supply asset in California, this dam serves as a testament to the ongoing efforts to manage water resources effectively in the face of changing climate conditions.
