Fishing Around Boulder In A Nutshell

Boulder Creek See Full Report

As of 6/26 Barker Reservoir was still spilling, but flows have come down nicely in the upper canyon above Boulder Falls. The sections from Boulder Falls up past Roger’s Park and Castle Rock up to Nederland are at a manageable level, and definitely worth checking out. The channel is small enough that it can be fished from the shore, but wade fishing is now an option in certain areas. The rest of the canyon is white-water so fish pockets from the shore and be careful. Some nice fish have been coming out of the town section, especially on streamers. One of our most successful rigs right now is a dry dropper combo using a Chubby Chernobyl with a small rainbow warrior dropped underneath. With all the off-color water, some type of worm pattern or larger stonefly pattern is a good bet to keep in the starting lineup.

South Boulder Creek below Gross Reservoir at Walker Ranch has been dropping nicely, and as of 6/26 was sitting right at 300 CFS. At 300 CFS and below wading is possible for most of this section. Try working the edges with something along the lines of a J.C. special, small Chubby Chernobyls, a small PMX or if there are BWOs out, a Mole Fly up top with about a two and a half foot dropper. Underneath good options would be Olive or Grey RS2’s, Copper Johns, BTS Baetis, Frenchies, WD 50’s, small 20 Inchers, Bishop’s Dynamite, and San Juan variations. Don’t forget about some of the upper stretches of South Boulder Creek as well. Flows have dropped in Pinecliffe and the Rollinsville area, both of which fish great this time of year. South Boulder Creek is going to really turn on as the flows keep coming down!

Clear Creek See Full Report

Flows are still cranking through the canyon, and much of the water in the canyon and even up past Idaho Springs is still straight whitewater. If you’re going to try to fish Clear Creek in the canyon, your only option right now will be to do it from the bank. The hardest part is just finding slow enough water to get a drift into. Heavy and high brush in the canyon can make much of the slower water along the banks inaccessible. Plan to drive around a lot and cover a lot of water to find the fishable spots. Worm, Stonefly, Midge and Caddis imitations are all pulling fish when you can get a decent drag free drift. Some of the very upper stretches of Clear Creek are also a good option this time of year as they will come down in flow first.

Big Thompson See Full Report

After a long stint of high water below Olympus, flows have dropped and it’s game on! The Big Thompson below Olympus Dam is one of the best options on the Front Range right now. Another option would be to check out the upper stretches of the Big T in the Park. The dry-fly bite has been solid, which makes it even better. We’ve been having the best luck on #20 adams and Mole Flies up top with UV emergers, soft hackle sow bugs and calico midges trailed below.

Blue River See Full Report

As of 6/26 flows were still up in the > 1000CFS range, which is a lot of water moving through the channel, but flows are on the decline. Wading is still a pretty tough proposition. The lower Blue below Green Mountain is also high but still somewhat wadeable.
Concentrate your efforts on the edges and any soft pockets you can find. With flows this high you can finally give 4x and 5x a spot on the starting lineup. With the bump in flows more shrimp are going to be dumped into the buffet line, so try to always work a Mysis pattern into the mix. It’s also a great flow to try heavy worm patterns like the Vegas Weekend or Jakes DB worm.
