Fish Creek is a small town with a nice bay that offers some very good fishing. The eastern shoreline of Fish Creek Harbor is Peninsula State Park. Fish Creek Harbor is very popular early in the summer as tons of smallmouth bass move into the bay to spawn. Smallmouth bass can be caught in the deeper parts of the bay in the summer and fall as well, but the first 2 weeks of June will usually offer the best fishing here. Some anglers do target perch, walleye and pike in this area as well.
