Fishing Report For: Blue River
September 19th. 2023
The Middle Blue River runs from below Dillon reservoir to Green Mountain reservoir. This section is probably the most popular because of it’s very easy access (including behind the Silverthorne Outlet stores). This section of the blue below Dillon is a Tail water fishery that sees a lot of fishing pressure throughout the Year. Midges, Mysis shrimp and annelids are the predominant food source for these rather large and elusive Trout.
Better fishing down stream of Silverthorne along HWY 9 headed towards Kremmling. There are numerous DOW access points along the stretch headed to Green Mountain. The Lower river begins below Green Mountain reservoir and confluences with the Colorado river 15 miles downstream, this lower section is best known for its “Jurassic Park” section that is only accessible by raft and a competent oarsman. There is wading access is limited just below the Green Mountain dam.
9/19/2023- The Blue River is one of Colorado’s best known tailwater fisheries. large and very wary Trout inhabit the 1st. couple miles below the Dillon reservoir. The Blue below Dillion and Green Mountain reservoirs are excellent fisheries, although the Trout can be finicky and small flies and light tippets are required. However there are VERY large trout in this section. The fishing here is done with mostly small Midges, BWO’s, Annelids, and Mysis shrimp Dillon reservoir is 100% full and flows around a 100 CFS which makes for perfect wading conditions from the dam all the way down to Green Mountain. If you enjoy sight fishing to large Trout then this river is right in your wheelhouse. Most of us prefer to fish down stream of the Outlet stores. There’s plenty of access down by the library…The river picks up some volume from several tributaries as it makes it’s way down to Green Mountain reservoir.
If you haven’t wade fished the Blue below Green mountain reservoir you are missing out! It can be a bit of a steep hike in and out, but the fishing is well worth the effort. There is very limited public access except right below the dam. Flow below Green Mountain Reservoir is just under a 1000 CFS right now. This is a great time to wade down there. Flows are perfect for the Jurassic Park float!
