Water Word of the Week: World Water Day falls on March 22, with a focus on providing all people with clean water and sanitation – resources that still elude some residents of California. Here, distributing water equitably for people and the environment is one of the state’s most challenging and critical areas for state leaders and water managers. So we’re making California Water Overview our Water Word of the Week. For more of the vibrant vocabulary of California water check out Aquapedia, our free online water encyclopedia.

What’s on Tap This Week: The State Water Resources Control Board meets Tuesday and Wednesday. On Thursday, the Delta Stewardship Council convenes to discuss important Delta issues. Be sure to check out our month-by-month calendar for the most up-to-date information on events put on by the Foundation and other organizations.

Water Resource of the Week: Due to the state’s increasingly unpredictable climate, long-range planning and conservation of water supplies is critical to California’s ability to withstand droughts, which are becoming longer and more intense. Conversely, as this winter has shown, the rivers that bring prosperity to California also can bring destruction when they fill with rainfall or snowmelt and burst over their banks. Check out the 10th edition of our Layperson’s Guide to California Water for a breakdown of the state’s water use and development history. 

Western Water, our flagship publication produced by Foundation journalists, is available online. Check out our most recent article: 

• California water agencies hoped a deluge would recharge their aquifers. But when it came, some couldn’t use it.
