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: 05-14-2015

Stopped for a hour at one of the National Forest pull-offs along Tolland Road west of Rollinsville. Water was surprisingly clear, with only a slight stain to it. Weather was coming in off the divide so the wind was pretty gusty and I was having trouble keeping tight with my euro-rig, so I switched over to a micro New Zealand Strike Indicator. I barely moved and had pretty continuous action on a size #16 jigged Hare’s ear along with a size 16 Rich Strolis brown micro-stone. I also caught a few fish on a larger caddis nypmph when I was dredging some of the deeper pools. If you’re looking to get away from run-off, getting higher up is a good option. Water was still moving pretty good for that section, but the helps push the fish into the edges and behind structure, so it almost makes it easier to figure out where to focus your efforts.
