Oh and thought this guideline would help for the Ottawa main. Paul, You should make a post and sticky it and perhaps add in for the middle channel too!
Here:
On McKoys:
Baby Face: +1 and lower. -1 is probably about the best level though.
Left Side Horseshoe: Lower levels (0 and lower) are generally the most fun, but its decent from roughly +2 and lower iirc
Right side horseshoe: Most enjoyable as wave hole at +3 to +4
Corner Wave: Good from +6 and lower
Phils: most pit like at 3-4, best wave like level at about 12
Sattlers: its great from roughly 15 and above, although its drop on only. the higher the level the better. I think there is a magic level where there is eddy service but the wave is flushy around 15.5
7-up hole or 7/8th hole: best from 7-8
On the lorne:
Garb: -2 to -0.5.... -1 is my favourite level.
Push Button: its straight up a hole from 0 to -1, and becomes more of a wave the lower you go.
Waikiki: I think 8ish is best
Buseater: surfable from 13 to 17. 13 becomes trashy. 16-17 is best. Correct me if i'm wrong anyone
On Butchers Knife:
Chopping Block: giver whenever you feel like it. 0 is probably a better wave like level. This rapid mellows out in high water
Lunch Stop waves: great for a surf kayak at high levels, like 18 and higher
On Coli:
I don't really remember when kahuna is fun. I remember surfing it at 15 or so and it was rowdy. Gladiator I don't know either.
On Blacks:
Left side: good at -3 and lower
Right side: probably best around 1.5 - 2
