I was fIshing there again this wed and thurs.
As a bassfishermen I have had every known type of algae on my line. From the green goo, to Elodea densi.

The whitish brownish crap getting stuck on everybodys line is Cottonwood that has been in the river long enough for Algae to grow on it!

BTW, its really slow at Bluecreek right now I only hooked 9 fish yesterday and 7 the day before, hardly worth the trip.
