David J. Guy, NCWA President

As the President of the Northern California Water Association (NCWA), David cultivates a shared vision in the Sacramento Valley for a vibrant way of life—working closely with the leaders in the region and an interdisciplinary team of experts to foster harmony and join together a world-renowned mosaic of natural and human abundance: productive farmlands, cities and rural communities, wildlife refuges and managed wetlands, and meandering rivers and creeks that support fisheries, people and an astounding landscape. 

For the past several decades, David has worked closely with policy-makers to draw a deeper connection among people in rural and urban areas by showcasing the special attributes of California’s special rivers and landscapes, including the Sacramento Valley, Yosemite National Park, Redwood National Park, and the Sierra Nevada. In this role, he calls on his experience in law, geological sciences, communications, and working with amazing people. David and his wife have traveled extensively and they split their time between the Sacramento Valley and the Sierra Nevada, with three children who all love food and cooking, the outdoors, music, and traveling.
