Okay, so I've run Bluegrass 3 times and the gage reports don't match the visual levels I've seen.
The first two times I ran it were the Saturday and Sunday of a weekend in August and on both Friday and Monday the recording said 302cfs. On Saturday the fin rock in the middle of the flake boof on the top rapid was under water but barely visible. The next day it was slightly higher and the rock was not visible. If Saturday really was 302 then Sunday would have been about 325.
So a couple weeks later I ran it again. On Friday, the recording said it was over 350, on Saturday, it was much lower than the other times (the fin was completely exposed). Then on Monday, the recording said 300. So this definitely doesn't jive with the flows from the other times I've been down. If the first day at 300 was right, I'd say this was about 250.
So my question is: Has anyone paddled this often enough on weekdays (when there is a reliably updated flow recording) to get a correlation between cfs and a visual marker, like the rock?
