I can attest to the ugly scene at Ft. Peck Reservoir in Eastern Montana, if you have never considered what that place might look like with miles and miles of mudflats showing, please at least take a look at the State of Montana and get a handle on the sheer size of Ft. Peck, it is huge. Yes, Griza is right, even during the drought, the corps continued to drain down Ft. Peck for the purpose of putting water in the lower Missouri and Mississippi systems for navigation. Shouldn't need to worry about upper Missouri flood control.
I live in a place that is situated near the upper reaches of Big Horn Reservoir, on the Big Horn River, dam is located at Ft. Smith, Montana. Big Horn Canyon National Recreation area is one of the least known about, but most beautiful areas in the the Nation.



Big Horn Lake impounds the super muddy Big Horn River which flows from the south out of the Wind River Range, and in fact, is known as the Wind River until it leaves Boysen Reservoir and the Wind River Indian Reservation and becomes the Big Horn River at a point just outside of Thermopolis called "wedding of the waters."
Now, below (north of) Thermopolis, the river becomes silted by irrigation, and runoff as it passes through a vigorous farming area stretching from Thermopolis past Greybull which is about 60 miles downstream. By the time the river flows into Big Horn Lake, it appears as muddy as big muddy herself.
Here is where the Montana/Wyoming water wars begins. What once was a free flowing river to the Yellowstone muddy as hell, now becomes a pristine clear water trout fishery below Ft. Smith, and in fact is one of the most widely marketed and recognized blue ribbon fly fishing waters in the world. Fly and float guide services erupted not only in Ft. Smith, but impacted the area all the way to Billings, etc.
We too have been having some drought issues, and guess what, not enough water to supply the trout fishery, and keep water in Big Horn Lake, so the upper end,(south) Wyoming's end of the lake became an ugly mud flat, and the war was on.
