Areal Flood Advisory

Statement as of 3:07 PM PDT on April 26, 2017

Expires 12:45 PM EDT on April 27, 2017


The National Weather Service in Reno has issued a

* flood advisory for...
a dam floodgate release in...
Placer County in central California...
Nevada County in northern California...
southern Washoe County in western Nevada...

* until 245 PM PDT Tuesday

* water management officials have increased the flow out of Lake
Tahoe on the afternoon of April 26th. The increase in flow will
lead to minor flooding along the Truckee River from the Lake Tahoe
dam to Truckee and abnormally high flows along the river through
Reno and Sparks. These high flows will likely continue into early
Summer.

* Impacts... minor flooding will cover sections of the Truckee-Tahoe
bike path along Highway 89 as well as portions of the path through
the Reno-Sparks area. Some backyards, basements and campgrounds
along the river near Highway 89 may be inundated by the high
flows. Campgrounds in the area are closed.

* These high flows will continue for an indefinite amount of time as
officials manage the water in the Truckee Reservoir system in
anticipation of higher snowmelt flows in may and June. Officials are
constantly monitoring the high flows and flood impacts.

* This will be the highest flow on the Truckee River from the Lake
Tahoe dam to Bear Creek at Alpine Meadows since February 1999.

Precautionary/preparedness actions...

The river is powerful, fast and cold. Please stay clear for safety.
Any unanticipated increase in flows could lead to flooding in areas
near the river.

... The flood advisory for snowmelt remains in effect until 945 am PDT
Thursday for Placer County...

* increased releases from Lake Tahoe will continue for a prolonged
period of time. This is being done to make room for future
snowmelt from a near record snowpack in the Tahoe basin.

* Minor flooding is expected along sections of the Truckee River
between Lake Tahoe and squaw creek. Below squaw creek... flows on
the river will be even higher due to snowmelt runoff from local
tributaries. This may cause some very minor flooding near the
river just above the city of Truckee as well.

* Locations impacted include the bike path and other low lying areas
from Lake Tahoe to just below squaw creek.

* This will be the highest flow experienced on this section of the
Truckee River since the Summer of 2006. Any changes to, or around,
the river channel since 2006 may result in unanticipated impacts.

* These flows will result in very powerful, fast, and cold
conditions that will be very hazardous. Keep people, pets, and
property clear for safety.


Precautionary/preparedness actions...

Stay away or be swept away. River banks and culverts can become
unstable and unsafe. The cold temperatures of
the water will result in rapid onset of hypothermia.
