We ran this river twice in packrafts at about 640 CFS and about 550 CFS. We did not see any warning sign for the fish diversion dam. We could not see a way to portage the fish diversion dam on river left. Plus, the metal grates just downstream of the low head dam were exposed several inches above the water surface. This made for a mandatory and difficult portage on river right. There is a floating 'fence' on river left made of long cylinders connected end to end on a cable that force anything that is floating out away from the concrete/steel structure and over the dam. Note also that just above the diversion dam the river splits around a small island. The left channel around this island also has a small low head dam, location 48.37985662270801, -120.2454820009975, which we did not get a good look at. I suggest running the right channel around the island and avoiding this smaller low head dam entirely. We ran the river twice: 6/4/2026 and 6/6/2026. The first trip we portaged both low head dams. On the second trip, we took the right channel and avoided the smaller low head dam entirely. No unavoidable wood hazards encountered, although there are lots of human engineered log structures along the shores, presumably to create fish habitat.
