Non-Canal Rideau River Charts

[Isoblue]

Does anyone have a good resource for nautical or depth charts of the non-canal portion of the Rideau river? Everything I've found online concerns only the canal portion and not the Hog's Back to Rideau Falls stretch which is where I primarily fish. I'm trying to pinpoint some fishing holes without diving in with a snorkel.

I highly doubt you'll find maps for that stretch as it's pretty much deemed un-navigable by boat.

So I figured. I was thinking there might be some obscure MNR, Military or engineer survey of the river somewhere that somebody knew about. Oh well! Trial and error it shall be then.

Navionics WebApp has some areas mapped out of that stretch. Looks like it is mapped from billings bridge to the north end of Brantwood Park at Clegg st
