Our Estes Park fishing report gives you the most up-to-date fishing information on the local area and Big Thompson River. Check in here before going fly fishing in Estes Park so that you know where to go, what to use, and how to make the most of your time on the water.
Upper Big Thompson:
The flow is 60cfs now below the dam. The water is getting low already as we expected, but the fishing has remained stready. Weather this weekend is a little cooler than the last several so that should make the afternoon fishing better. Mornings and evenings have been the best times lately. Good Yellow Sallies, PMD and caddis hatches are happening most days. Ants and hoppers are also plentiful and are a good option as well. Stone fly and Caddis nymphs are very active sub surface.
Hot Flies: For dry flies - PMD, Yellow sallies, Terrestrials and Caddis patterns. Nymph setups include Rainbow Warrior, CDC Pheasant Tails, Hot Head Sow Bugs, Copper Ribbed Rs2, Pats Rubber Legs, Hares Ears, Blue Poison Tung and Perdigons have all been good.
Private Water Waterdale Ranch:
The flows are perfect and the fishing is very consistent . The fishing is stellar right now throughout the property. Cooler weather this weekend should create great conditions. Chubby/emerger combos have been very good.

Nymph rigs are going to be the most productive. Hopper/dropper rigs with bigger nymphs are good as well. Caddis and Stonefly nymphs are all over the place.
Hot Flies: BWO, Blue Poison Tung, Mole Flies, Pheasant Tail w/CDC, No Mercy Midge, Juju Bees, Grey Sparklewing Rs2, Copper Ribbed Rs2, Mayhem Midge and Hares Ears all being good choices.
Mary’s Lake and Lake Estes:
The flow into Lake Estes is 61 cfs and the river through the golf course is fishing well in the mornings. The rain of the last couple afternoons has brought up the flow some. Afternoons at the inlet are definitely slower on the hotter days. Mary's Lake and Lake Estes have had pretty steady action the last couple weeks.
