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

With temperatures rising well above normal through Wednesday,
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 streams, and Walker, Carson, and Truckee River flooding
summary:

* On the WEST WALKER RIVER, minor flooding is expected from the
  Walker River Canyon into Antelope Valley and high flows through
  Smith Valley and downstream through Wilson Canyon. There is
  minor flooding occurring just below Wilson Canyon.

* On the EAST WALKER RIVER, minor flooding is ongoing and
  expected to continue from just above Strosnider Ditch to the
  confluence with the West Walker.

* The WALKER RIVER THROUGH MASON VALLEY AND YERINGTON is expected
  to crest just below moderate flood stage. Minor flood stage
  will be reached Wednesday morning and flow will peak out late
  Friday.

* No flooding is expected below Weber Reservoir at this time.

* SMALL STREAMS draining the eastern Sierra could see flows in
  excess of 2 to 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 to Truckee along Highway 89 and nearby areas. This is
  likely to be confined to areas immediately adjacent to the river
  with impacts confined to campgrounds and bike trails.
