...Snowmelt Flooding Concerns Increase Over the Eastern Sierra
and Western Nevada...

With temperatures rising well above normal through Thursday,
snowmelt will accelerate across the eastern Sierra. The increase
in snowmelt will cause daily rises in many small streams from Mono
County north through the northern Sierra. Snowmelt flow typically
peaks in smaller streams late in the evening or overnight.
Farther downstream flows will continue to increase through next
week as the smaller streams add water to the main rivers.

Small stream and Walker, Carson, and Truckee River flooding summary:

* On the WEST WALKER RIVER, minor to moderate flooding is
  expected from the Walker River Canyon into Antelope Valley and
  Smith Valley, as well as downstream through Wilson Canyon.

* On the EAST WALKER RIVER, very minor flooding is possible below
  Bridgeport Reservoir. Farther down the river, minor to moderate
  flooding is expected from just above Strosnider Ditch to the
  confluence with the West Walker.

* The WALKER RIVER THROUGH MASON VALLEY AND YERINGTON is expected
  to reach major flood stage. Flooding greater than that
  experienced in 1983 and 1986 is expected and may persist for a
  prolonged period of time.

* Below Weber Reservoir minor flooding is possible if releases
  from the reservoir need to be increased.

* SMALL STREAMS draining the eastern Sierra could see flows in
  excess of 3 times their current flows causing flooding near the
  streams from southern Mono County north through the Tahoe Basin
  and into parts of Sierra and Plumas Counties.

* The upper parts of the CARSON RIVER...INCLUDING THE SOUTHWEST
  CARSON VALLEY...are likely to experience minor flooding of farm
  and ranch lands.

* The TRUCKEE RIVER will likely see minor flooding below Lake
  Tahoe through the city of Truckee and nearby areas. This is
  likely to be confined to areas immediately adjacent to the river
  with impacts confined to campgrounds and bike trails.
