Hydrologic Outlook
National Weather Service Grand Junction CO
344 PM MDT Fri Apr 19 2019
...Rises on mid to lower elevation rivers and creeks possible through
this weekend...
Above normal temperatures, especially temperatures staying above
freezing at night, have allowed the snowpack at mid elevations to
melt at an accelerated rate.
At this time, rivers across eastern Utah and western Colorado are
not forecast to reach flood stage but rather just approach or
reach bankfull conditions.
Increases in river stages lead to much higher river flows making
for swift and unpredictable currents. Debris in the water could
create numerous snags. Water temperatures will be quite cold with
the introduction of the snowmelt.
If recreating or working in or near high flow waterways, use
appropriate safety gear. Unstable banks along fast moving
waterways may quickly give way and should be avoided.
