Topographic map - A2F - 01-10-2013 07:44 AM
Hey Folks,
I was thinking?
Does anyone know of any sites that have Topographic maps in Southern Ontario? (Mainly Peel Region - but more specifically, "Professors Lake" in Brampton) that are FREE?
I remember spotting written detailed info online awhile back - but never thought of saving it at the time.
I'd like to find other lakes too (that I often fish).
Anyway, I appreciate any help I can get...
Thanks again,
Rob

Interesting find here...
This document says Professor's Lake is 42 FEET...

While, if you type in google "Professors Lake Max Depth", it answers with 42 METERS..
I can't see a former gravel pit turned spring fed reservoir be 42 FEET DEEP?
Still in search of this elusive map (if there is one out there on the interwebs)

Is it a topo map you're looking for or a hydrographic chart?
Topo maps use contour lines to show land features, hills and valleys. A hydro chart shows what's under the surface of the water, channels, humps and depths. Most charts especially for navigation are sold and not free, atleast not that I have found. The place to buy them is on University Ave and I think it was Adelaide, not positive of the address, I used to work near there and knew the building.

Have you played with Fish-On Line?
http://www.web2.mnr.gov.on.ca/fish_online/fishing/fishingExplorer_en.html
It has info on many Ontario lakes............. a small % also have hydrographic (depth profiles).
Your "Professors Lake" is not listed but thousands more are.
Takes a while to get the gist of using it, but it can be helpful.
Tip - I've noticed that sometimes it won't show depth contours when selected.......... then the next time you visit - it does............. apparently an "undocumented" feature..............
