BLA, as mentioned Everts is the best if you are interested in the upper end of Pool-4; however, if your interest is in the lower end of lake Pepin, the Pepin city launch is excellent and only 43 miles from Menomonie. Take hwy 25 south from Menomonie, through Durand, to hwy 35. Go west on hwy 35 to Pepin. Turn left at the BP gas station and follow the road down the hill and cross the railroad tracks. The public launch is just to your left as you cross the tracks by the Pickle Factory restaurant. There is an excellent free public access launch and rest-room facility there, including a fish-cleaning station. This launch will provide quick access to lots of fish. Let us know how the bite is for you.
