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

  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.


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.
