South Boulder Creek: A western trout fisherman’s paradise and beyond!

Merry Christmas from Colorado Fly Fishing Reports!  We hope you are out on the river or enjoying the most joyous of times with friends and family.  This weekends Colorado fly fishing forecast focuses around Boulder a town that has a lot of cool things to offer even the most distinguished of anglers…

Take for instance the fact that Boulder fly fisherman can enjoy breathtaking and gorgeous views of the Flatirons, hot hippie chicks, lots of extremely high alcohol content breweries, the greenest of grasses, a great bar and restaurant scene and of course even better trout fishing!

Sure every now and then, you might have to deal with a distraught and quite possibly angry downtown Boulder Bum while you try to fish your way behind the CU campus, but from the center of what some like to call a liberal and idealistic bubble surrounded by realty, anglers can access some of the best trout streams on Colorado’s Front Range. Just minutes Boulder anglers can gain access to the St. Vrain River, Big Thompson, Rocky Mountain National Park, Boulder Creek and our personal favorite South Boulder Creek, not to mention a wide offering of warm water fly fishing for trophy bass and sight fishing for carp…

Even better for Boulder anglers is that the fly-fishing season is year round! South Boulder Creek below Gross Reservoir fishes well throughout the year and often times hits ideal flows during the winter months. As of December 25, 2014, South Boulder Creek is running at 81 CFS. At 81 CFS the flows are prime for searching the water with dry flies like the classic Parachute Adams size 18-22, Micro Stimulators size 18-20, Elk Hair Caddis size 18-22. Believe it or not prospecting the stream with dry flies on warm and sunny days can be more than effective.

Still though, a skilled nymph fisherman will hook the majority of fish this time of year. Fishing with 7.5 nylon leaders dropped with 4x to 5x tippet should be adequate for fooling the often times somewhat technical trout of South Boulder Creek. If we could fish one fly below the surface this time of year it would most definitely have to be a size 20-22 black or red Zebra Midge! This weekend the forecast for beautiful Boulder, Colorado is looking warm and sunny so why even waist time thinking about it? Get out and fish!

Tight Lines,

  1. Boulder Creek and S. Boulder Creek are spitting distance from my front door. Thanks for the nice write up. I didn’t have the opportunity to fish in 2014 due to old man health issues but I’ll be back as soon as I get a little sunshine on my shoulders.
