South Boulder Creek flows still hold around 80 at the Gross tail water providing good fishing even though it is January. This tail water is usually too low to fish most of the winter, so keeping the flow up above 80 all winter has provided for some excellent fishing just 12 miles away. There are almost three miles of water in Walker Ranch, so crowding is dealt with by just hiking away. The cold waters below Gross are running clear, and the fishing has been good to damn near awesome. The bug diversity has faded to small midges only sporadically. Some days there are tons, and others almost none at all. Small black stones will start to hatch next month, and already the nymphs are active along the bottom. Nymphing has been best all day long with the best luck at a dry fly chance happening between 11 am and 2 pm. Look for midges to get thicker as we creep toward spring. This tail water is slow to wake up this time of year, so there is no need to get going too early. Hitting the water by 10 am is plenty early, and it really cools of in this canyon when the sun gets low. As long as flows are above 25 cfs there is fishing to be had at Walker Ranch on SBC. Farther downstream Eldorado Canyon has been consistently good with shallow dry dropper rigs. Flows downstream of Eldorado are super low and will be low all winter. There are some deeper holes that will be your best bet for finding fish when the flows are way down. In Eldorado State Park, nymphing some of the deeper plunge pools is also a way to fish this steep canyon. Flows here are low and clear so be sure to have some 5x or even 6x for best success. Terrestrials will still work on warm days so maybe try an ant or beetle with a pheasant tail, or zebra midge underneath. Dry flies will still get the attention of the fish down here. Recent trips to the Gross tail water have been slamming with Poison Tungs, Rainbow Warriors, and small black stones. Other flies catching fish are Copper Johns, Yarn Eggs(big chartreuse), and black or olive streamers. Eldorado Canyon has been the best bet for anybody with only a couple of hours to get out, while Walker Ranch is best when you bring your lunch. Downstream of Eldorado the waters are extremelyStill fishing great!
