...Peak snowmelt runoff is done for the Spring 2017 season...

..Streams and rivers expected to continue to recede through the end
the week...

...Reservoir releases out of Boysen and Fontenelle Reservoirs will
keep The Big Horn and Green Rivers running at high levels
through the end of the week...

Snow water equivalents (SWEs) are between 15 and 18 inches at the 9,500
to 10,000 foot elevation along the Wind and Green River Basins.
There is a warming trend starting Friday and Saturday over the mountains with
above average temperatures lasting through the middle of next week. However,
by the middle to the end of the warming trend, there will be not enough SWEs
in the remaining snowpack below 10,000 foot elevation to cause significant
runoff for any additional major rises in streams and rivers. Therefore, the
peak snowmelt runoff is done for the Spring 2017 season.

Streams and rivers will continue to recede through the end of the week.

Reservoir releases out of Boysen and Fontenelle Reservoirs will
keep the Big Horn and Green Rivers flowing at high levels through the
end of next week. Cities and towns below the reservoirs to include
Thermopolis, Worland, Basin, and Green River will continue to have localized
lowland flooding with the high flows.
