DROUGHT INFORMATION STATEMENT
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
843 AM PST Mon Feb 13 2017

...Drought improvement in portions of California, but extreme
drought conditions continue in portions of Santa Barbara, Ventura,
and Los Angeles Counties...

SYNOPSIS...

After 5 consecutive years of drought, many areas in California
since October 2016 have received beneficial rain and snow which
has resulted in major drought improvement across many areas of
the state. A sliver of D3 (Extreme Drought) remains across
Santa Barbara and Ventura Counties due to low reservoir levels,
low streamflow, and low groundwater levels. Currently the U.S.
Drought Monitor classifies 0.73% of the state of California
in extreme drought. The U.S. Drought Monitor classifies drought
into five categories of increasing severity: Abnormally Dry (D0)
...Moderate Drought (D1)...Severe Drought (D2)...Extreme Drought (D3)
...and Exceptional Drought (D4).

On January 17, 2014 California Governor Jerry Brown declared a
drought state of emergency in California. The full text of the
emergency proclamation can be accessed at:
www.gov.ca.gov/news.php?id=18368.

On April 25, 2014 California Governor Jerry Brown issued an executive
order to redouble state drought actions. The full text of the
executive order can be accessed at: www.gov.ca.gov/news.php?id=18496.

On July 15, 2014 the California State Water Resources Control Board
approved an emergency regulation to ensure agencies and state
residents increase water conservation. Local agencies could ask
courts to fine water users up to $500 per day for failure to
implement conservation requirements. The text of this regulation can
be accessed at:
www.swrcb.ca.gov/press_room/press_releases/2014/pr071514.pdf

On April 1, 2015 California Governor Jerry Brown ordered a 25 percent
cut in urban water use in the first ever mandatory statewide
reductions. The text of this regulation can be accessed at:
gov.ca.gov/docs/4.1.15_executive_order.pdf

Supply conditions have improved in some parts of the state to allow the
State Water Project to increase certain allocations. However on may
9, 2016 California Governor Jerry Brown signed executive order b-37-16
to maintain in full force the orders and provisions contained in his
January 17, 2014 and April 25, 2015 executive orders.
