Important. as of may 5 2026 there is a terrible strainer on Lampson falls on right line and more wood blocking entrance to main line down the main falls. Our group ripped down from Lampson falls at 650cfsa. at this level Lampsons falls was quite low with no main line other than middle we dput in below the falls. we played at an unamed play spot before the 1/3 mile flat water paddle before old bridge. just after Lampsons falls. At around 650cfs Thanks was quite the large hole, I couldent imagine it any bigger. next was no thanks, there is also a line that goes right around the island that is not mentioned, this could be a horrible line, at higher waters there is a potential for a go arond at both the left sides of the thanks rapids. Both Should be properly scouted before ran. At this level mikes hole was a breeze. then snot rocket we went right line. the next 2 rapids we snuck through with no issues at this level. we walked north country boof. the sive at the boof main line was looking worse than ever. After northcountry boof the waster was really low and unfun till the take out in Degrasse. jut a note about the portages, there are large dec signs marking the portage trails, the actual trails have not been kept up and practically dont exist.
