Being a geek for data, I’m always on the lookout for more information on the lakes I fish in NW Wisconsin, most of which are in the ceded territories. The Great Lakes Indian Fish and Wildlife Commission has posted all of their walleye survey data on the website below:

Click on Biological Services and select inland fisheries to see the counties surveyed.
Their surveys include fall recruitment data and spring popluation estimates dating back about 4 years. The data is much more comprehensive than anything readily available from the Wisconsin DNR. Mille Lacs is included as well because it is also in the ceded territory. Hope you guys find it as useful as I have.
