Muskrats in the Bismarck Area

I am in Bismarck for the weekend and looking to shoot some muskrats. My new Henry Varminter .17hmr with a leupold vxI 3x9x40 wants to spill some blood. It sounds like it is flooding all over here so there must beĀ some prime muskratĀ  hunting. You dont have to give up your muskrat honey holes but if you could point me in the right direction it would be appreciated.
