Update Monday, 04/13: CANCELLED DUE TO HIGH WATER. The Head River is already at the 100th percentile maximum flow with more rain on the way this week. I will repost this trip later when levels have come down. If you still want to paddle this weekend, I'll probably post a trip on a local GTA river instead.
---I'm planning to do a long day trip of around 30 km starting on the Head River northeast of Sebright and continuing downstream on the Black River into the town of Washago. The first 16 km until Highway 169 a mostly flatwater section interspersed with short whitewater drops - I have not been on this section before. The next 3 km after Highway 169 is the usual whitewater play area on the Black River where the river loops around through many Class I-II rapids, ending with an optional more challenging technical chute. The final 9 km is almost all flatwater, save for a canyon with turbulent boils and large standing waves, and we will end the day by paddling against the current up the Green River, where the water suddenly transitions from dark and tannin-stained to green and crystal clear.
If you want a shorter day, it's possible to take out after the whitewater play section and cut out the final 9 km of paddling. We will arrange the shuttle to accommodate everyone's preference for where they want to end the trip.
