If you don't mind driving a few kilometers you can take the secondary highway part way up the hill in West Peace River and head north. When you cross over the Whitemud River take the district road on the north bank and head east to the mouth of the Whitemud and the Peace. My brother-in-law tells me he fishes it often for Walleye and Pike. I think it's about 80 Km.from Peace River. Use this mapping resource for finding your way around.
