Army Corps Of Engineers Holds October Update On Missouri River

(KCCR) — The U-S Army Corps of Engineers it’s October update on the Missouri River Thursday. Kevin Grode with the Missouri River Water Management Division of the Corps of Engineers says October, so far is on track with runoff three times more than average…

“Now we’re expecting three times average largely in part to the tributaries that are continuing to flow much above-average due to the September rains, along with the soil moisture conditions being extremely wet; and this all limits infiltration from any rain events.  Through the first 10 days of October, the runoff has been what we expected; about 3 times average.  For November and December our forecast indicates that we are expecting inflows to be about twice average.”
If the Corps’ runoff forecast holds it will tie the all-time record set in 2011 of 61-million acre feet. Mike Swenson with the Corps says releases from Oahe Dam will likely be increased slightly…

“Oahe Rreservoir is at elevation 1614.2; down 0.7 feet since the end of September. The reservoir is 6.7 feet above the base of the annual flood control zone.  Releases from Oahe are currently about 61,000 C-F-S and will be increased to 62,000 C-F-S next Tuesday.”
John Remus Chief of the Water Management Division for the Missouri River says the main stem system will not be cleared of 2019 runoff this year…

“We will not have all of it evacuated by December, we will have the majority of evacuated, but the remainder we plan to evacuate over the winter.”  “How long you think it’ll take to have it completely evacuated?” “Right now we’re looking at either the end of January or the first part of February.”
The Fort Randall reservoir pool dropped just over three feet in the month of September.
