Water connects every part of our community, from local farms and businesses to the people who call it home.
On World Nature Conservation Day, SSJID recognizes the importance of protecting the natural landscapes and waterways that support a reliable water supply. Through planning, infrastructure investment, and management, we work to balance today's needs with the long-term health of the communities we serve.
Stewardship is more than a responsibility. It's a commitment to ensuring this essential resource remains available for generations to come.

As temperatures rise and more people spend time outdoors, it's important to remember that canals are not safe places to swim or play.
Water may appear calm on the surface, but strong currents can exist below, creating dangerous conditions that can quickly pull a person underwater. For your safety, never enter a canal.
Pet owners should take precautions as well. Keep dogs on a leash and discourage them from drinking the water or investigating unfamiliar materials along the banks.
Help keep your family, friends, and pets safe by staying away from canals and remaining aware of your surroundings.

Did you know that a water shortage in 1915 helped shape SSJID's future?
This year marks the 110th anniversary of Woodward Reservoir, which was completed in 1916 near Oakdale after District leaders recognized the need for additional water storage following a dry winter and limited supplies.
Named after one of SSJID's founding board members, the reservoir increased the District's storage capacity by 36,000 acre feet and strengthened water reliability throughout the region.
Today, Woodward Reservoir remains an important part of SSJID's water operations, continuing the work it was built to do, helping provide a dependable water supply for farms and communities.
