FLOOD POTENTIAL OUTLOOK
Great Salt Lake, Sevier, Virgin and Price/San Rafael and Duchesne
The 2014 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 below average and range from 65-80
percent of average across most of the state. Recent snowfall has improved
conditions in the headwaters of the Provo and Utah Lake basins, but below
average conditions persist.
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.
