Weekend Update: Colorado’s Blue River below Dillon

Our Colorado weather is quickly transitioning into winter and tail waters will soon be our streams of choice for pursuing trout in the off season.  This weekend our attention turns towards the Blue River below Dillon Reservoir.  Many anglers have a love and hate relationship with the Blue River and rightly so as this river can be finicky and at times impossible to predict.

Fishing on the blue river

But after doing a little homework anglers can find themselves some great fly fishing along Highway 9 between Silverthorne and Kremmling.  This is some of the most scenic country in Colorado, complete with elk, moose, bears and a host of other critters.  And of course big brown, rainbow and cut bow trout call the Blue River home.


Early in the winter season, anglers can have the blue river all to themselves as the harsh weather of the Colorado mountains keeps many fisherman off the water.  Right now the Blue is flowing at a ripe 238 CFS below Dillon Reservoir and there is an abundance of Mysis shrimp, midges and mayflies crawling about the stream.  Our favorite winter time nymph patterns include Mysis shrimp in hook sizes 18-22, Eggs in sizes 16-18 and Black Beauty’s and other thread midges in hook sizes 20-24.  The occasional midge hatch may come off mid-morning on the warm and sunny days so be sure to come to the stream with Brook’s Sprout Midge in hook sizes 20-24 as well as Griffith’s Gnats in hook sizes 20-24.
