I fish it regularly as it's only a few minutes from home. When the water levels are normal, it can get REAL skinny in spots due to gravel bars and such. Most boats on the river are flatbottomed and for good reason.
My sled is flat bottomed and this past steelhead season I drug bottom in a few shallow spots if that tells you anything.

In the lower part of the river you can get away with a deeper hull.
