South Boulder Creek Fishing Report Header

South Boulder Creek

South Boulder Creek has to be one of the most scenic rivers within a half hour of downtown Boulder. This creek starts up in the Indian Peaks near the Moffat Tunnel and gains momentum on its journey towards the cool deep waters of Gross Reservoir. Below Gross Reservoir, South Boulder Creek becomes a great tailwater flowing through the Walker Ranch open space. This area is the most popular section of the creek due to the great hatches and consistent flows through the summer months. The access to this section is fairly easy taking visitors up and over Flagstaff Mountain, onto a dirt road, and into the wilderness.

There is no road following the creek so if you are looking for some solitude this is the spot. The aquatic insect activity in this part of the creek is incredible, it sees hatches of Caddis, BWO’s, PMD’s, Midges and great Terrestrial fishing.  South Boulder Creek might be your best chance for a big wild brown in Boulder County.  Every year anglers routinely catch browns in excess of 18 inches. The river heads east through some public and private water before dumping into Eldorado Canyon State park. After the plunge pools of Eldorado, the creek mellows out upon entering the flats of Boulder and eventually joins Boulder Creek.

Fishing Report Date: 07-31-2014

SBC is on fire right now.  At just a hair over 120 cfs, anglers need to get this fishery on their radar and fast!  It is fishing incredibly well with a variety of rigs and at this flow, it is well suited for both dry fly fishing as well as heavier nymph rigs.  Try dry dropper rigs on the seams and in the softer water to the sides.  Try larger nymphs and deeper indicator rigs in the fast stuff.  Fish are holding everywhere so no cast is a bad one.  Get out there and fish it while it’s hot!

Dries: 12-16 Crystal Stimulator, Parachute Caddis 14-16, Ext. Body Dunn (PMD) 14-18, CDC Biot Comparadun 16-18, Ben’s BDE 18, and Ant Dries.

Nymphs: Tung Swing Caddis 16-18, Deep Six Pupa 14-16, Barr Emergers 16-20, Tung Midge (red) 18-20, RL Stones (brown/ollive) 8-10, Purple Psycho Princes 14-16, and Pheasant Tails 14-18.

Also, don’t be afraid to swing a smaller black or olive streamer through some deeper runs or near the banks.  You might find something larger than expected!
