The Milwaukee River is one of the largest tributaries in Eastern Wisconsin and has runs in both the spring and fall. In the fall, the Milwaukee receives a large run of Chinook salmon, with many of the fish topping the 20 pound mark. The fish usually continue coming in through the end of October and beginning of November. The Steelhead usually follow the Chinook in to feed off the eggs and feast on the dying Chinook. These Steelhead average 8-12 pounds, with some fish in the 15 pound range. Spring is probably the best time to target the Steelhead, as the higher flows usually bring in more fish. Flies bright in color usually bring in more fish and some ferocious strikes.
