Milwaukee charter fishing heats up in mid May. This is when Coho salmon action really starts to get rolling. The Coho salmon is the number one stocked salmon in Lake Michigan and only Lake trout our stocked at higher numbers. This is the time of season to target Coho salmon and also delivers the highest catch rate per trip. Most of the limits happen when Coho fishing. They are also the best tasting fish that we catch during the season. Book a trip in the last 3 weeks of May to get in on the early Coho salmon action.
