Quote(s) of the Day: This is about as perfect as it can get, perfect summer day, perfect weather and lots of fish to top it off.

Fishing Highlights:

Today was about as good a Tuesday can possibly be because I was able to fish with Charlie and Sal for our yearly summer trip. Flows came up to 200 cfs in the past few days, so we had to be patient through the morning hours while the fish remained stubborn and selective. Regardless, the guys put several fish in the net and got a lot of quick hits throughout the Railroad Beat. Patience is definitely the name of the game in the mornings right now. After lunch we migrated up river to the Boulder River Ranch beat. Right off the bat Sal and Charlie doubled up on a pair of nice rainbows. The fish were looking up, eating grasshopper dry flies and lightly submerged emergers and soft hackles. By the time I got a fish unhooked from Charlie's line, I was running to get another one off of Sal's. We had several huge trout during the afternoon that will leave a mark on our memory: Charlie hooked a beast that literally exploded our rig and Sal had a massive cutthroat on that we nearly landed.

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. 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 one hot summer on the river! Time to put the waders away and bust out the gravel guards and wet wading sandals.  Try an Amy’s Ant (size 10-12) or California Blonde (size 10-16) to fool hopper eating fish. The days are getting shorter and the nights are getting cooler, fall is around the corner.  The fishing is great.  Clear skies and 60+ degree weather. The water temperature was between 48-51 degrees and Crystal Clear.
