Flows are more level, but still low. Fish will primarily be in the deepest water available and can be spooky, especially on sunny days. ABove the Falls, flows are even less, and it has been very tough here. Lower down has been better, but you'll still need to bring along a thermometer, as water temps can get hot quickly. Primary hatches have been: Midges, Drakes, Caddis, Yellow Sallies, PMD's and BWO's. ...
Boulder Creek
● Live flow from USGS · water temp from sample (no temp sensor at this gauge)
flows back after recent rains (FRA current) · clarity great — largely escaped the muddy water · 'fishing remains excellent,' dry-dropper the way to go · fish get very surface-oriented late AM
RMA/FRA June: 'Flows are level, making for good fishing. Water clarity is a bit stained, but it hasn't seemed to bother the fish. Fish have spread out into the pockets and zones that aren't as deep — start with a dry-dropper.' All of the creek fishing well, above the falls has easier wading. Orodell ~78 cfs (drought-level, ~29% of median, below typical runoff). Primary hatches: midges, caddis, BWOs. Dry: Hi Viz No See Um BWO, AR's BWO Adult/Emerger, Para Ext Body BWO, Hi Viz Beetle, Superman Caddis, Foam Run Caddis, Micro Chubby. Nymphs: Zebra Midge, Juju Baetis, Arnott's Pocket Drone, Spanish Perdigon, Sweet Meat Caddis, BTS May in BWO, Tung Poudre Pupae, RS-2. Today (Sun Jul 5) ~91°F plains, sunny and hot — fish mornings; scattered storms return Tue–Wed.
FRA (current): 'Flows are back thanks to recent rains, and the fishing remains excellent — Boulder Creek largely escaped the muddy water and clarity is great.' Dry-dropper the way to go; fish can be especially surface-oriented late AM. Primary hatches: midges, caddis, Yellow Sallies, PMDs, BWOs. All of the creek fishing well (above the falls = easier wading). Water temp mid 50s. Weekday pattern: today (Sun Jul 5) ~91°F plains, sunny and hot; scattered storms Tue–Wed, heat rebuilds late week. No road follows the creek — good solitude spot.
