Isle Royale Forums

Heading over to the island for a McCargoe/Birch Island to Chippewa Harbor trip from the 17th to 25th that will hit every inland lake and portage along the way (Except the Richie-Chippewa Portage). I've found a lot of good fishing info on here but was wondering if anyone knew where I could find bathymetric maps of the inland lakes? I'm a little old school and don't use electronics but do like to have an idea of the underwater structure, especially for the few lakes that have walleye. Not the biggest deal but figured if they exist someone here would know where to find them. Don't see anything on the MI DNR site and all the recreational maps lack inland bathymetry unlike the BWCA maps I'm used to.

Ended up answering my own question and found an app that has many of the inland lakes on it. Only lake I'm planning on fishing that it doesn't have is Whittlesey.

Looking forward to the trip if not the forecasted 10-20mph winds every day of it.

I gather you are getting to CH via the counter clockwise loop through Siskiwit then Whittlesey? I did this years ago but started paddling from Rock Harbor. The canoe only campgrounds on Ritchie, Wood and Whittlesey are very isolated, although total Island occupation will of course be low. You can't avoid northerns in Ritchie. I think there's Walleye in Whittlesey and of course Lakers in Siskiwit.

Have a great time. Stay safe & warm.

In 3 trips, everything I've caught on Whittlesey has been along the north side between the east end of the long island and the campground. Usually just trolling down once and ill catch more than we can eat in any day. I think we hit 5 walleye this summer in 1 pass and tossed back as many pike.
