Springtime on the Mainstem Trinity brings big water delight. On the Pigeon Point Run we begin one mile up the North Fork to enjoy it's clear green water and the contrast of it's smaller size. Once entering the mainstem one meets long trains of towering waves very different from the river's summertime appearance.
Good Morning America appropriately has the first bottoms-out drop. The Slot is an impressive nearly river-wide hole with one reasonable choice of where to go. Huge angling waves take the raft straight through Zig Zag, and the larger waves of Hells Gate arise unexpectedly. Hell Hole, still impressive, is unrecognizable as the summertime waterfall. Sailor Bar's angled waves bank the raft around the corner. It takes a lot of water to cover the biggest rocks of Pinball, requiring technical backpaddling, and Fishtail is long with the biggest hole of the day.
Just downsteam from Big Flat, the rapids join to make a single rapid over a quarter mile long. Lickety Splat has a fun swirling, boiling eddy. Big French Creek Rapid boasts the biggest waves on the river, and some very impressive, though luckily avoidable, Moby Dick-sized holes.
May is the most reliable time for big water because large dam releases are scheduled to scour the river and send hatchery salmon and steelhead to the ocean.
