Quote(s) of the Day: Now that fish is a dandy!

Fishing Highlights:

Kirk and I started off low on the railroad beat, picking our way through pocket water, fishing to picky trout, reluctantly feeding on midges. We picked some fish near the edges, but it took until about 11am for the fishing to really turn on, when the sallies, drakes and pmds emerged. From that point forward we took fish on dries, emergers, nymphs and streamers about every 5 minutes until the end of the day. There were so many highlights, from fishing double dries and getting them slapped on the surface on nearly every cast, to landing 4 fish well over 20". The fish were big, healthy, strong - the day provided perfect weather, and perhaps the best is the sincere comradery between a group of addicted fisherman.

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 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.  The fishing is fantastic.  Clear skies and 60+ degree weather. The water temperature was between 56-59 degrees and Crystal Clear.
