Utah Rivers To Reach Highest Levels This Weekend

With temperatures forecast to reach into the mid-80`s this
weekend... Utah`s rivers fed by mid and high elevation watersheds
will reach their highest levels of the year. However...flooding is
not anticipated at this time.

Utah`s major river systems will once again experience below average
runoff again this spring.  This is the fifth below average runoff
year, dating back to 2012.  The meager runoff volumes are due
primarily to dry low snowfall...dry soils...and a premature warming
during February and early March.

Upper elevation watersheds including the Bear...Weber...and Provo
rivers are forecast to see 83%...78%...and 75% respectively. Lower
elevation watersheds did not fare as well due to the premature
February warming period.  For example Emigration Creek and City
Creek which feed the Salt Lake Valley are forecast to produce 20%
and 65% respectively.

Although the majority of this year`s hydrologic picture has been one
of dry conditions and low flows...Utah`s small to mid sized
reservoirs are in relatively good shape...averaging near 80% of
full. Larger reservoirs will take multiple years to fill.  These
include Bear Lake...Lake Powell...and Scofield Reservoir.

With the increase in flows this weekend...it is imperative that we
understand these waters are incredibly hazardous.  Streams and
rivers fed by spring snowmelt runoff are flowing swift...cold...and
dangerous. If you or your children happen to fall into a mountain
fed stream hypothermia is expected within minutes.

Please monitor your children and use prudent judgment when
venturing near these dangerous waterways.
