Starting in Silverthorne from Dillon Reservoir, the Blue River is a popular tailwater fly fishing river that heads north to Kremmling at the confluence with the Colorado River. The first couple miles from the Dillon Reservoir dam are Gold Medal fly fishing stream that area catch-and-release only. This section is known for year-round fishing for very large rainbow trout and brown trout. While fishing and midge hatches are year-round especially close to the dam tailwater, the best caddis season is from mid-June through mid-August.
There area numerous fly fishing access points for the Blue River, but surprisingly, many fishermen just park at the Factory Stores in Silverthorne right off US70 via Exit #205.
While most fly fishermen focus on the tailwaters of the Blue River, there are about 10 miles of the upper Blue River above Dillon Reservoir that are also quite productive for 12 to 16 inch trout found in the pools and riffles.
