I fish there quite a bit. I have fished this river for the last 25 yrs and spent the last two weekends up there. Last year there was a fish kill and I estimate 2/3 of the population was lost. The good news is that the remaining fish are healthy and strong. The average size fish is around 15" with the upper end around 19". The summer time temps can be brutal in July but the crowds are lower. I have not fished the winter there in about 15 yrs. It can be very cold. May/June then Sept/Oct are good times to camp on the river. With regards to the crowds the weekends are always busy. There are on average 3 to 5 guide boats on the river during the summer on Sat-Sun.
