Water conservation: How did Californians do after mandate (Part II)
How is California’s water conservation after last report? The October number just arrived, so here they are: In September, Californians reduced water usage by 18.3% vs. 2013, in October, 19.5%. They are quite consistent with the numbers since June, when the water conservation mandate was lifted, in the 17%-22% range. These numbers indicate Californians continue to put in the effort to conserve water after the mandate, and the result is about 20% reduction for total potable urban water use since June.

From Brown to California Native Charm
The brown lawn has been an eye sore to the owner of the house for quite a while. He had been wanting to replace it with something more beautiful, but did not know where to start. Since California’s drought five years ago, he put in his effort to conserve water, turning off the sprinklers. Sure enough, the lawn went brown.

In May 2015, the State Water Board adopted an emergency regulation requiring an immediate 25 percent reduction in overall potable urban water use. Now one year has passed, how well have Californians been doing?

California’s drought over? Not yet; Still need to conserve water? Yes
Do all the rains brought about by El Nino end California’s historical drought? The answer is No. While the rains definitely helped ease the drought, they did not end it. As you can see from the graph below, statewide snowpack stood at way lower than average from 2012-2015; in 2015, that level went down to a really low 5%. In Spring 2016, while the rains brought by El Nino helped put the level back to 85%, one season of rain fall simply is not enough to offset the deficits accumulated from 4 years of drought. During the past 4 years, groundwater levels dropped to historical lows; in parts of the state it was as low as 100 feet below previous historical lows. It will take much more than what we receive so far to recover the storage.
