256 PM PDT MON MAY 2 2011
...SPRING SNOWMELT TO CAUSE EASTERN SIERRA AND WESTERN NEVADA RIVERS
AND STREAMS TO RISE SIGNIFICANTLY THROUGH FRIDAY...
...NO SIGNIFICANT FLOODING EXPECTED UNTIL LATER THIS SPRING...
SNOWMELT DUE TO WARM TEMPERATURES AND MUCH ABOVE AVERAGE SNOWPACK
WILL CAUSE INCREASED FLOWS ON CREEKS...STREAMS AND RIVERS THROUGHOUT
THE EASTERN SIERRA AND WESTERN NEVADA THIS WEEK. SLIGHTLY COOLER
TEMPERATURES EXPECTED THIS WEEKEND WILL SUBDUE RISES UNTIL NEXT
WEEK...WHEN WARM WEATHER IS EXPECTED TO CAUSE MOST RIVERS AND
STREAMS TO RISE EVEN FURTHER.
NO SIGNIFICANT FLOODING IS EXPECTED THIS WEEK. THERE MAY BE SOME
LOCALIZED MINOR LOWLAND FLOODING ON TRIBUTARY SMALL CREEKS AND
STREAMS THROUGHOUT THE REGION...ESPECIALLY IN AREAS BELOW THE MOST
ACTIVE SNOWMELT...CURRENTLY IN THE 6000 TO 7000 FOOT RANGE IN THE
CENTRAL SIERRA.
ALSO...THE WEST AND EAST FORKS OF THE CARSON RIVER ARE EXPECTED TO
HAVE SIGNIFICANT RISES TO ABOVE CHANNEL CAPACITY...OR
BANKFULL...THIS WEEK. THE WEST FORK OF CARSON RIVER BETWEEN
WOODFORDS CALIFORNIA AND GENOA NEVADA IS EXPECTED TO RISE TO NEAR
BANKFULL BY WEDNESDAY MAY 4TH. THE EAST FORK CARSON RIVER BETWEEN
MARKLEEVILLE CALIFORNIA AND GENOA NEVADA...INCLUDING THE
MINDEN-GARDNERVILLE AREA...IS EXPECTED TO RISE TO NEAR BANKFULL BY
FRIDAY MAY 6TH. ONLY VERY MINOR LOWLAND FLOODING IS EXPECTED IN
THOSE AREAS THIS WEEK.
THE HIGHEST FLOWS OF THE MELT SEASON ON THE CARSON AND TAHOE BASINS
ARE CURRENTLY EXPECTED BY MID MAY...WHILE THE HIGHEST FLOWS ON
THE WALKER BASIN ARE EXPECTED BY EARLY JUNE. THERE WILL BE A HIGHER
THREAT OF FLOODING ON THOSE BASINS AS THE MELT SEASON PROGRESSES.
BASINS WHICH COULD EXPERIENCE FLOODING THIS SPRING IN THE EASTERN
SIERRA NEVADA AND WESTERN NEVADA INCLUDE...
UNCONTROLLED LAKE TAHOE TRIBUTARIES...
UNCONTROLLED TRIBUTARIES OF THE TRUCKEE RIVER ABOVE RENO NEVADA...
EAST FORK...WEST FORK AND MAINSTEM CARSON RIVERS AND TRIBUTARIES
ABOVE LAHONTAN RESERVOIR...
WEST WALKER...EAST WALKER AND MAINSTEM WALKER RIVER AND TRIBUTARIES
ABOVE WEBER DAM...
MONO LAKE TRIBUTARIES...
UPPER OWENS RIVER TRIBUTARIES IN MONO COUNTY...
HUMBOLDT RIVER ABOVE RYE PATCH DAM IN PERSHING COUNTY.
ALL EASTERN SIERRA RIVERS AND STREAMS WILL BE RUNNING VERY
COLD...DANGEROUSLY SWIFT AND TURBULENT THROUGH LATE JUNE. IN ORDER
TO PREVENT DROWNINGS...ANYONE VENTURING NEAR THESE RIVERS AND
STREAMS...INCLUDING RAFTERS...KAYAKERS... SWIMMERS...CAMPERS AND
ANGLERS...SHOULD BE ESPECIALLY VIGILANT OF THE HAZARDOUS CONDITIONS
THEY PRESENT. IT WILL BE VERY DIFFICULT TO ESCAPE THE TURBULENT
WATERS IF YOU FALL IN. DUE TO THE ICY WATER TEMPERATURES...ARMS AND
LEGS WILL BECOME NUMB QUICKLY CAUSING AN INCREASED THREAT OF
DROWNING. AS CHILDREN ARE DRAWN TOWARDS WATER...THEY ARE ESPECIALLY
VULNERABLE AND SHOULD BE MONITORED CLOSELY IF NEAR A RIVER OR
STREAM.
