I couldn't find a lot of info about hunting. If you've come across any of the info I have, no doubt you've run across plenty of info about fishing in the area. There are over 1000 lakes in Otter tail county.
I did find a bit of info on the MN. DNR site... This was the most recent deer density map I could find. It looks like the region supports a very high population of whitetails. Particularly to the North, and East. Just a guess, but I'm putting you in the 240, to 241 area.

I should add that those #'s are going to look different after this Winter... The DNR has released deer feeding funding for the first time since 96... We've had bad Winter for the whitetails.
