Try this site out for depths and distance, takes a minute to figure out, but once you get on to it, it's pretty cool.

1. accept the disclaimer.
2. familiarize yourself with the options at the top of the map (hover your mouse of the icons).
3. switch map to XL size (top right of map is where this option is)
4. zoom in to your area of interest
5. on the left side of the screen is some tabs, click on the layers tab to make it current
6. click the natural features folder, then water and navigational aids, then water features, then great lakes bathymetry (shows depths), and make sure lake ontario bathymetry option checked. You can also turn other things on here that are helpful, such as the markers and bouys.
7. refresh your map, and you should see the depth contours
8. To see the depth of each contour pick the icon on top with an "I", then click on the contour line and the information will appear on the left side of the screen (in meters...to get feet, simply multiply the number by 3.27)
9. If you want to measure the distance between two points (in case you want to pace your distance from shore) there is an icon at top, looks like two arrows with a tape measure. Pick first point, then pick second point, and it gives you the exact distance. From surveying I know that I can pace 100m within 2m accuracy by stretching my step just a bit. Takes a bit of practice, but helps for stuff like this. If you have a GPS unit, this gives coords as well and you can plug them into it.
Cheers, hope this helps.
BTW, this looks like a spot where the ice might be sketchy, not sure though as I have not been there, be careful.
