Colorado Stream Update: Visibility is still limited to 12-18" here so your ability to read "fishy" water will be crucial in your success on the San Juan.

Current Conditions at San Juan:

Despite the lack of sight fishing here the fly fishing has been great. Both walk-wading and drifting have been working well, but if possible drifting the SJ can result in a 50 fish day! Leeches, San Juan Worms (who woulda guessed?!) and Scuds are all working well as lead flies on nymph rigs. Trail that with a small midge emerger like a Top Secret or Chocolate Foam Emerger and you'll have yourself one helluva day! Local guides are reporting that BWOs are making their presence known on a limited basis as well, but for the remaining month of March midges will continue to be the main hatching insect. Visibility should clear up within the next 3-4 weeks as well.

Despite the colder temperatures the river is flowing steady. Fifty fish plus days on the stream are not uncommon right now.  The fishing is great.  Clear skies and 56-59 degree weather. The water temperature was between 36-39 degrees and Slightly Off.
