Fishing Highlights:

Robert and his son Rad took advantage of ideal conditions today on South Boulder Creek. Right from the beginning Rad, just about to start 1st grade, rolled some really nice rainbows laid up off a plunge pool on a hopper-dropper rig. After getting a feel for it, this little man put some great fish in the net. Robert who fished our river as kid growing up, was right at home after shaking off the cob-webs. Right before lunch, Robert put a stud rainbow in the net taping 21X14. In the afternoon, Rad should us how productive our stream is by the diverse amount of insect he was finding on the banks and Dad got a moment to pull on some really nice trout. Before the rain, a great hatch of PMD's gave us some really visual eats. Needless to say, a day I will not soon forget! Thanks fellas, and we hope to see more of the Dullnigs!

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!  The fishing is fantastic.  Overcast skies and 60+ degree weather. The water temperature was between 52-55 degrees and Crystal Clear.
