Flow: 116 cfs
Water Temperature: HIgh 30 and low 40’s
Hatches: Midges and blue-winged olives
14 Day Forecast: Look for low flows and technical fishing. Anglers can expect to see sporadic hatches of midges. Target the traditional winter lies (slow, deep pools) where you’ll find the largest concentration of fish. The best fishing is between 11 a.m. and 3 p.m.
Tips and Other Information: Denver Water continues to hold back water in an effort to fill Cheesman Reservoir. Look for flows to remain between 75-125 cfs for another couple weeks. Currently the lake is still 4,000 acre feet from the top (about 95% full). My guess is Cheesman Dam will spill normally during the first part of May. For the meantime, my recomendation is to concentrate your efforts in the transitional zones that drop off into the deeper runs. In the a.m., flies of choice have been #22 Mercury Midges, #24 Black Beauties, and #24 Top Secret Midges. When you visually see the “big” spring midge coming off, adjust your tactics and techniques to match the hatch. A size 18 pupa trailed by smaller pupa is what I recommend. Make sure you drift your pupa mid column! Look for a nice blue-winged olive hatch each afternoon between 1 and 3 p.m. Overcast days provide the best dry fly fishing. Regardless of the conditions, sub-surface fishing in the afternoon is good with an assortment of Baetis nymphs.
