Colorado Stream Update: Boulder Creek continues to fish lights out!

Current Conditions at Boulder Creek:

Midges and Mayflies are everywhere on Boulder Creek as the unusually warm spring weather has really turned up the temperature on Boulder Creek. We're seeing sporadic Caddis here and there but nothing that would constitute a full blown hatch. Fish are feeding in traditional feeding lanes-- along seams, riffles, and tail outs-- and are taking both dries and dropper. Parachute Adams in sizes #16-22 are the preferred pattern to use up top while your dropper can range anywhere between a #20 JuJu Baetis, JuJuBee Midge, RSII, Barr's Emerger, or Biot Emerger. And here's a little guide's secret to fishing Boulder Creek-- there are some serious piggies through town...

Our local streams close to Denver and Boulder are producing great fly fishing days. The water is low and clear and the fish are hungry. Fly fishing trips have been great. Spring is here and it’s time to grab the rod and head for the mountains and foothills! This is some of the best action of the year on Boulder Creek! The fish have not seen any pressure in months and good hatches of midges and blue winged olives keep the fish rising.  The fishing is great.  Clear skies and 60+ degree weather. The water temperature was between 44-47 degrees and Crystal Clear.
