If Pepin went no wake, I’d prefer it be Friday afternoons through Sunday evenings between June 1st and August 1st. I could maybe fish it again on weekends. As of now, I do 90% of my fishing during the week on Pepin.
Just like BK hinted at, there’s no such thing as “no-wake” on Pepin that I’m aware of. The “no-wake” zones on the way to Wabasha below Pepin are only from Memorial Day – Labor Day and are not based on flow or river levels.
