The combined fall-spring spawning run of steelhead rainbow trout on Wisconsin's Bois Brule River for the past season was a bit above average, DNR officials report.
A total of 6,404 steelhead swam up the river to spawn — both in fall 2018 and spring 2019. That’s a little above the 29-year average of 6,216. In recent years the runs have fluctuated between 3,500 and 8,500.
Steelhead that swim upriver in fall are staging to spawn and are joined by more fish in the spring, when spawning actually occurs, before the bigger fish drop back to Lake Superior to spend the summer.
This season’s fall run has already begun. The trout fishing season on the Brule is open through Sep. 30 upstream of Highway 2 and Nov. 15 downstream to Lake Superior.
