Rock Lake
A prairie lake in the Pembina Valley west of Pilot Mound, Rock Lake is a stocked walleye water that also holds northern pike and carp. Angler catch reports consistently show walleye and pike as the top species. It is a quieter alternative to the bigger name lakes nearby, with decent shore and small-boat access.
