The growing leadership of women in water. The Colorado River’s persistent drought and efforts to sign off on a plan to avert worse shortfalls of water from the river. And in California’s Central Valley, promising solutions to vexing water resource challenges.
These were among the topics that Western Water news explored in 2018.
We’re already planning a full slate of stories for 2019. You can sign up here to be alerted when new stories are published. In the meantime, take a look at what we dove into in 2018:
Everyone who diverts water is required to report to the State
Water Board the amount they used. But Louis and Darcy Chacon
reported an amount that just didn’t make sense. The Chacons
reported they used more than 1 trillion acre-feet of water
annually from 2009 to 2013, more than is available on the
People in California and the
Southwest are getting stingier with water, a story that’s told by
For years, water use has generally been described in terms of
acre-foot per a certain number of households, keying off the

The long-time rule of thumb: One acre-foot of water would supply
the indoor and outdoor needs of two typical urban households for
Fashioned after the popular California Water Map, this 24×36 inch
poster was extensively re-designed in 2017 to better illustrate
the value and use of groundwater in California, the main types of

Redesigned in 2017, this beautiful map depicts the seven
Western states that share the Colorado River with Mexico. The
Colorado River supplies water to nearly 40 million people in
Arizona, California, Colorado, Nevada, New Mexico, Utah, Wyoming
and the country of Mexico. Text on this beautiful, 24×36-inch
map, which is suitable for framing, explains the river’s
apportionment, history and the need to adapt its management for
urban growth and expected climate change impacts.
As the state’s population continues to grow and traditional water
supplies grow tighter, there is increased interest in reusing
treated wastewater for a variety of activities, including
irrigation of crops, parks and golf courses, groundwater recharge
and industrial uses.

Our 24×36 inch California Water Map is widely known for being the
definitive poster that shows the integral role water plays in the
state. On this updated version, it is easier to see California’s
natural waterways and man-made reservoirs and aqueducts
– including federally, state and locally funded
projects – the wild and scenic rivers system, and
natural lakes. The map features beautiful photos of
California’s natural environment, rivers, water projects,
wildlife, and urban and agricultural uses and the

An acre foot of water equals about 326,000 gallons, or enough
water to cover an acre of land 1-foot deep.
To put it another way, an acre foot of water is enough to flood a
football field 1-foot deep (a football field is roughly an acre
An acre foot of water is a common way to measure water volume and
use. In California, an acre foot, or 326,000 gallons, can
typically meet the annual indoor and outdoor needs of one to
two average households. But, in more recent years,
an acre foot began serving even more households.
This issue updates progress on crafting and implementing
California’s 4.4 plan to reduce its use of Colorado River water
by 800,000 acre-feet. The state has used as much as 5.2 million
acre-feet of Colorado River water annually, but under pressure
from Interior Secretary Bruce Babbitt and the other six states
that share this resource, California’s Colorado River parties
have been trying to close the gap between demand and supply.
