Tobin Lake has some drive to lodges.
The ones I am thinking of are Pruden's Point Resort on the N shore of Tobin and
Tobin Lake Resort on the S side right in the village area and last but not least
Thunder Rapids Lodge on the Sask. River near the hydroelectric power station.
All of these guides and lodges in the Tobin Lake area should be able to tell you were to find and what to use for
the big one.
If you wanted to try some fishing in the S for big fish, be it walleye, pike, perch or carp the folks at G & S Marina at Last Mountain Lake should find them for you.
They also have cabins to rent there.
