Actually the Rideau valley conservation authority considers it the biggest tributary of the Rideau. It used to be stocked with bass and Walleye up until the 70's.

Big spring walleye run.
Bass, pike and musky year round.
Great for kids with lotsa sunfish and rock bass, with many parks offering easy access.
My favourite is to wade the rock gardens and pools on the west side of Richmond (just barely up stream of the village and wade your way down until it gets too deep -around Fowler street), but I grew up there so I'm biased. small spinners, plugs and topwaters. Crayfish imitations during the molt are deadly(August).
There is a boat launch just upstream of the Richmond Centennial Golf course. From there you can go downstream a little ways, and upstream a great distance into the fen, but eventually you find a beaver dam.
A dry year can see it get quite stagnant and murky, esp if the runoff from the farms is proportionately heavy.
Send me a PM if you want to chat, I usually fish it a half dozen times a year.
I caught my first fish on the Jock when I was 7. It was a 5 lb Wallye- I caught at the McBean st bridge. I was so afraid of it I had to flag down a car for help.
