Notice to Navigators: Missouri River

By Dede Smith | February 11, 2022

Missouri River Surveys

 

Please see attachments for the below areas of concern from recent hydro surveys conducted on the river.  As a reminder, mariners are urged to exercise caution and to transit areas of shoaling at their slowest safe speed and proceed with caution.

 

Gavins Point releases will be temporarily increased to 14,000 cfs today at noon due to forecasted low river stages and potential impacts to intakes below Gavins Point.  MRRCC plans to maintain releases of 14,000 cfs until February 16, when releases will return to 12,000 cfs.  As always, we will continue to monitor basin conditions and make changes as necessary.
