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.

It was a perfect summer evening to go check out SBC below Gross Revervoir. Flows have dropped in the past week, and it’s just on the cusp of getting really good! Flows were around 325 CFS, which is still moving pretty good, but opens up enough water to make it interesting. Once it drops to 300 and below, look for SBC to be a great after work option!

I primarily concentrated my efforts behind any structure and in back eddies. Some of the fish were right on the bank, others were out just on the edge of the fast current. The higher water seems to be putting the bigger fish at ease, as the averages size of the fish caught were larger than normal.

My rig consisted of a weighted worm pattern and a jigged hare’s ear dropped about three feet below a small Chubby Chernobyl. The majority of the fish came to net on the worm pattern, but the #16 hare’s ear saw it’s share of action as well. Had probably half a dozen refusals on the chubby, with two or three fish that committed.

All in all a wonderful summer night with plenty of colorful wild rainbows to hand.
