                       FLOOD POTENTIAL OUTLOOK

Great Salt Lake, Sevier, Virgin and Price/San Rafael and Duchesne
River Basins.

The 2016 spring runoff flood potential due to snowmelt is not high at this time for any
of the basins mentioned above.

Current snow conditions in Utah are near to above average and range from 100-150
percent of average across the northern half of the state, and 130-165 percent of
average in the Virgin and Sevier River Basins.  Near and above average precipitation,
particularly in December and January, and near to below average temperature conditions
have contributed to near normal seasonal precipitation conditions throughout much of
the state.

It should be emphasized that snow accumulation conditions could change quite a
bit before the runoff begins. Although spring temperatures affect the pattern of
snowmelt runoff and consequently the magnitude of peak flows, peak flows also
roughly correspond to volumetric flows. It is also important to keep in mind that
an extended period of much above normal temperatures or heavy rainfall during the
melt period can cause or exacerbate flooding problems in any year.
