I paddled with some friends from Savanne at the north end of Lac de Milles Lacs through that lake, Brule, etc., Windigoostigwan, and leaving Windigoostigwan, the river was navigable.
We took out under the highway, because below that point we guessed it would be dubious paddling. From there I think we dumped our gear with a friend who had come to meet us with a car, and we walked along the hydro line? or an old portage trail? to come out near the park office by the beach (Dawson Trail office). This was all before internet stuff and Google maps etc.
So I think you might want to talk to the park staff about where to take out from French lake and walk to the French River.
That said, what are you going to do when you get on the Savanne river and head up that twisty thing? The old portage from Savanne to Lac de Milieu is pretty much lost to highway, road, and pipeline construction, logging, and forest fire. (Check out Eric Morse, Canoe Routes of Canada Then and Now, where he quotes a forester who witnessed the closing of the passage after a fire in the late 1960s). so travelling east-northeast from Savanne river to lac de Milieu, to the unnamed lake, to Coldwater lake will take a lot of research and slogging.
check out this amazing blog about a guy who was probably the last person to traverse that area by canoe (okay, a kayak that he dragged through there (muskeg, bog, slash, etc) by sheer strength of will alone:https://predictablylost.com/2013/10/05/angle-to-key-west-the-lake-of-ice-925/
I thought it would be an amazing retirement project to reopen this route to navigation. Maybe you're the one to do it?
