The Garrison Dam is only 5.1 feet away from the same elevation it was in 2011 and with recent increased releases in the Missouri River — the water is rising.
There’s usually rocks that you can see along the banks… not anymore… and if you look closely a few tiny trees are in the water.
So I wanted to dig a little deeper and find out for you what these high waters are doing.
Currently the release from the Garrison Dam is about 44,000 cubic feet per second…. an average for June — 25,000 cfs.
Mike Swenson, Missouri River Basin Water Management, says, “This year a lot of the runoff is driven by the mountain snowpack.”
It’s different than 2011 — the release then was 150,000 cfs.
Now, according to Swenson, the peak flow into Garrison was last week, but the peak in the reservoir will be in about 2 weeks from now.
The river may be high and is causing erosion along the banks, but residents in Hoge Island are not worried.
Norm Hoiland, Hoge Island Resident, says, “I haven’t got insurance yet so hopefully it doesn’t come.”
Angie Haider, Hoge Island Resident, says, “I don’t really know if I can say I’ve really seen the effects of high water.”
Haider says that everyone has a different story to tell — like her neighbors to the north they have water 3/4 up their banks… that’s bad news… but her and Hoiland say the high water is getting rid of the unwanted sand bar.
Haider says, “It’s getting smaller as the years go by — which is exciting too. Nobody really wanted the sandbar it has not been a fun contribution that the flood left.”
At one point this sandbar was out another 100 yards.
The water will only rise a little more and shouldn’t cause any major problems.
Hoiland, says, “5 feet would make a person get a little worried.”
To get to the flood stage — we would roughly need 70 to 75 thousand cfs and the current forecast is not indicating any floods.
The rain that we got last night will only increase the reservoir and some of the tributaries slightly… meaning it would take a lot of rain for any major floods.
We still have the capacity to handle more water.
