Eau Claire (Wisconsin R. trib)

This river has a odd range of flow. The section below the dells peaks out in the 3500+ cfs range when it begins to be quite pushy and gets bony at below 350 cfs.
The main section of the dells drop will starts to get nasty, hole gets big at second drop and buggy water gets intense, at 900+ cfs, but can offer cheap thrills down to 85 cfs. A far right option ,class III-, opens up on the dells proper at above 2000 cfs and is runnable up to about 3500 cfs. These are some of my best estimates for runnablity.
