Public Information Statement
Issued: 7:32 AM PST Dec. 5, 2016 – National Weather Service

... An adjustment has been made to the flood level for the new Flood
Warning point at White River at r street...

The adjustment to the flood flow level for the Flood Warning Point
White river at r St. From 6,000 cubic feet per second (cfs)to 5,500
cfs was implemented today, December 5, 2016. The flood flow or stage
is the level at which flood warnings are issued by the National
Weather Service. Additional evaluations have indicated that flood
impacts could be expected with flows starting at the 5,500 cfs
level. Due to the changing nature of the stream channel of the lower
White River, there is a fair amount of uncertainty regarding at what
river level the flooding begins. This evolving nature of the river
will likely mean continued adjustments to the flood levels as we see
what the actual flood impacts are under high water conditions in the
coming months and years.

Flood warnings for the White River r St. Gage will address flooding
from Auburn down to the confluence with the Puyallup river,including
the cities of Auburn, Pacific, and Sumner. This area has seen an
increasing flood threat over the last several years due to changes
in the stream bed. Here are the flood levels for the three flood
categories that are in effect as of December 5, 2016:

Minor flood flow/Flood Warning level... ..5,500 cfs
moderate flood flow... ... ... ... ... ... ... .8,000 cfs
major flood flow... ... ... ... ... ... ... ... 10,000 cfs
