Quote(s) of the Day: I can't imagine spending a day better than this in Colorado - perfect weather in the middle of summer casting dry flies to these big rainbows is perfect!

Fishing Highlights:

Fishing with Arthur today was a real treat because the weather was perfect and we had the whole place to ourselves. We started off fishing the lower ranch (railroad beat) and immediately had two nice fish in the net. Water levels came up a bit recently and definitely made finding fish in the shallow riffles more challenging. We frequently switched from a double nymph rig to dry dropper depending on the conditions. Half way up the beat Arthur hooked two massive rainbows - one which spit the hook quickly during a tarpon-esque jump...but the other fish, which I think was ten pounds, ran us all over the river. This huge fish fought for ten minutes before sprinting downstream, only to be remembered by our imagination. None-the-less, a ton of fun. The afternoon was ideal because scatter thunderstorms with light rain brown yellow sallies, grey drakes and pmds. We caught fish on dries, emergers and nymphs in every run or soft seam. By two o'clock we'd lost count. Overall, epic day!

Lots of insects are on the water! This is some of the best fly fishing close to Denver right now. We are seeing regular hatches of Pale Morning Duns, Gray and Green Drakes, Mahogany Duns, Caddis, Yellow Sallies, and Golden Stones.  The evening hatch has been something you just don’t want to miss. The shallow riffles at Boulder River Ranch are bug factories this season! The late morning and early afternoon have been producing some outstanding dry fly fishing. Dry flies and droppers are the way to go! It summer at Lincoln Hills, the big fish are on the feed and many big fish in the 4-6 pound class have been hooked and our fly fishing trips have been fantastic. Work the water in between major runs and riffles, sometimes the odd pocket will produce a trophy fish. The caddis hatch is on fire! Try using a big Elk Hair Caddis with Jay Zimmerman’s Banksia Bug dropped off the back. Look for the caddis to start popping in the afternoon. The fish are looking fat and healthy! Many nice fish in the 16-22” range have been hooked! The big fish are on the feed! Anglers are reporting hooking numerous brown and rainbow trout in the 5-10 pound range. This is your best shot at a World- Class trout fishing experience close to Denver. It is grasshopper season! Fish are taking hoppers tight to the banks with reckless abandonment! Try an Amy’s Ant (size 10-12) or California Blonde (size 10-16) to fool hopper eating fish.  The fishing is fantastic.  Partly Cloudy skies and 60+ degree weather. The water temperature was between 48-51 degrees and Crystal Clear.
