Flood Warning

Flood Statement
National Weather Service Reno NV
1013 AM PDT Sat Jun 24 2017

...The Flood Warning continues for the following rivers in
California...

  West Walker River Near Coleville affecting Mono County

...The Flood Warning continues for the following rivers in Nevada...

  Walker River Near Mason affecting Lyon County

Very warm temperatures into early next week will maintain increased
snowmelt in the Sierra with rapid runoff persisting in the upper
portions of the Walker River basin.

Snowmelt will result in continued high flows on the West Walker
River. Peak flows will occur overnight into the early morning hours.

Increased releases from Bridgeport Reservoir will maintain high flows
on the East Walker River.

As a result...flows into and below the Mason-Yerington area on the
mainstem Walker River will remain high through early next week. The
peak level depends on efficiency of continued upstream flood plain
attenuation...reservoir management and when the reservoirs fill.
Based on the latest river data...minor flooding is likely through
Mason/Yerington with moderate flooding below Yerington through the
Wabuska area. Major flooding is still a possibility below Yerington
to near Weber Reservoir.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

These river forecasts are based on forecast rainfall and temperature
conditions at time of issuance. If actual conditions vary from these
forecasts...river conditions will vary accordingly.

The National Weather Service in Reno has extended the

* Flood Warning for Small Streams for...
  Snowmelt in...
  Southern Mono County in northern California...

* Until 1230 AM PDT Tuesday

* Prolonged high temperatures will continue rapid snowmelt in high
  elevation basins of Mono County where significant deep snow is
  still abundant. Stream flows are expected to remain elevated
  through early next week. Lower temperatures by the middle of next
  week will decrease these flows.

* Daily peaks the next several days are likely to be lower than
  previous days, but still exceed the capacity of stream banks.

* Earlier, we received multiple reports from law enforcement and
  emergency officials of raging creeks and streams affecting some
  trails, campgrounds, roadways, and even a few bridges throughout
  the eastern Sierra in Mono County. If you have plans to recreate
  or travel in this area, it is advised to check if your location
  has been impacted.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Flooding is occurring or is imminent. It is important to know where
you are relative to streams, rivers, or creeks which can become
killers in heavy rains. Campers and hikers should avoid streams or
creeks.
