PUBLIC INFORMATION STATEMENT
NATIONAL WEATHER SERVICE SEATTLE WA
128 PM PST MON MAR 2 2015

...CHANGES IN THE NATIONAL WEATHER SERVICE FLOOD LEVELS FOR THE
PUYALLUP RIVER BASIN HAVE BEEN IMPLEMENTED...

THE NATIONAL WEATHER SERVICE (NWS) IN SEATTLE...IN COORDINATION WITH
PIERCE COUNTY...HAS IMPLEMENTED ADJUSTMENTS TO THEIR FLOOD WARNING
LEVEL FOR THE PUYALLUP RIVER NEAR ORTING FLOOD WARNING POINT. THIS
IS DUE TO FLOOD MITIGATION EFFORTS BY PIERCE COUNTY THAT HAS REDUCED
THE FLOOD THREAT AT UNUSUALLY VULNERABLE LOCATIONS NEAR ORTING. HIGH
RIVER FLOWS THIS YEAR HAVE CONFIRMED THE SUCCESS OF THESE EFFORTS.
THEREFORE THE THREAT OF FLOODING NO LONGER OCCURS AT THE LOW
THRESHOLD OF 4500 CFS BUT AT THE MUCH HIGHER LEVEL OF 10000 CFS AS
IN PREVIOUS YEARS. MODERATE AND MAJOR FLOOD LEVELS REMAIN THE SAME.
THE NEW FLOOD LEVEL WENT INTO EFFECT MARCH 1 2015.

AS OF MARCH 1 2015...THE NEW FLOOD LEVEL FOR THE PUYALLUP RIVER NEAR
ORTING WAS RAISED TO:

FLOOD FLOW (MINOR FLOOD)        10000 CFS

THE MODERATE AND MAJOR FLOOD LEVELS REMAIN THE SAME:

MODERATE FLOOD                  13500 CFS
