The preservation and active management of Northern California’s groundwater resources is critical to the economic, social and environmental fabric of the region. As part of ongoing efforts to achieve sustainability, water leaders throughout the Sacramento Valley have made a concerted effort over the past decade to assess Sacramento Valley groundwater resources, both for groundwater levels and quality—and to then actively manage our water resources—both surface and groundwater—to assure sustainable water supplies for cities and rural communities, farms, fish, birds and recreation.
Groundwater resources are critical to the region, with groundwater providing nearly 30% of the region’s water supplies, with this percentage greatly increasing during dry years and during sustained droughts.
