About Oconto River
The Oconto River in northeastern Wisconsin flows from headwaters in Forest County to Green Bay (Lake Michigan), with the lower river hosting a strong spring run of steelhead and lake-run brown trout. The upper river above Stiles holds resident brown trout. A solid Lake Michigan tributary fishery with less pressure than the Wolf or downstate Driftless waters.
Regulations
Wisconsin Fishing License required ($20 resident + $10 trout/salmon stamp = $30). Spring steelhead season on the lower river. Verify Oconto County special-regulation sections in current Wisconsin DNR trout regulations.
