More fish go thru that spillway than u would think. Biologist have said the amount of fish caught in a year is not a drop in the bucket compared to what goes out the spillway. I have also heard that on average 80 % of harvestable fish are either caught or go thru the spillway in one year. Harvestable meaning above legal size limit. With that being said, why in the world would they move the length down to 11 inches! I know I have gotten way off topic but it's just something to think about. Also, I really don't know what to think about biologist after hearing there butla reports the last few years.
