Hydrologic Outlook
National Weather Service Grand Junction CO
927 AM MDT Mon May 22 2017

...INCREASED FLOWS ON THE LOWER GUNNISON RIVER THROUGH THE
WEEK WILL CAUSE RIVER LEVELS TO RISE TO NEAR BANKFULL...

Releases from the Aspinall Unit will cause an increase in flow and
river levels for the lower Gunnison River this week. Peak
releases should be reached by May 23 or 24. The target flow for
the the Gunnison River near Grand Junction will be 14,040 cfs,
near bankfull, for a two day period.

Expect flows through the Black Canyon to range from 10,800 cfs to
12,000 cfs. Flow for the the Gunnison River near Delta are
forecast to range from 12,800 cfs to 13,400 cfs.

After the 2 day peak target is met the flow will be reduced to
meet half bankfull target flow of 8,070 cfs at the Gunnison near
Grand Junction gauge.

Increases in river flows make for swift and unpredictable
currents. Debris in the river could create numerous snags. Water
temperatures will be quite cold. 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.
