The leaves have dropped but fishing is still good throughout the state of Colorado. Several tailwaters are fishing well with and assortment of dry flies and nymphs. Sporadic mid-day Trico hatches continue through Halloween and the "olive" hatches have been spectacular each afternoon between 1 and 3 p.m. During the non-hatch periods, it's hard to go wrong with egg/midge (Baetis) combos.
Many of the state's fabled freestones are fishing well too. Midges and blue-winged olives are keeping trout active from 10 a.m. to 3 p.m. As an added bonus, the streamer fishing has been very good as of late.
