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: 03-10-2015

Just when SBC was turning on and fishing great, the flows were abruptly dropped to just over 10 cfs. This makes fishing very tough on SBC. Low flows and clear water mean small bugs, light tippet, and long leaders. Fish will be congregated in the good pools and holding water. They will not be spread out like they normally are. Find good water and you’ll find fish. Although there are better options for fishing at this flow, if you are set on trying SBC bring 7x and an assortment of Juju midges, JUJU Emergers (NEW & HOT FLY), and small tailwater tiny’s in olive, red, and black. Very limited dry fly activity right now, but have a few midge dries just in case. As soon as they raise the flow here again, the bite will be on big time. Probably a couple of short weeks away. Call the shop if you want to check what they are doing with the flows.
