Colorado Stream Update: Flows and clarity will be touchy for a little bit

Current Conditions at North Fork Public:

The North fork of the South Platte will continue to see touch and go flows and water clarity through the early part of the summer. Due to good amounts of natural snowpack, It is unlikely that Robert's tunnel sends any additional flow down the North Fork. With these conditions it can be tough to get a proper presentation. As of late, local snowmelt has provided a nice bump in flows. Fishing has been fair. Trout have began to spread out, moving away from deep holding water and into the riffles with the warmer weather. A hopper dropper setup has been moving alot of fish. Patterns like RS2's, PT's, and San Juan worms have been working consistently.

Fly fishing reports have been fair to good. The fly fishing is on! Try smaller midge and mayfly patterns.  The fishing is fair.  Partly Cloudy skies and 48-51 degree weather. The water temperature was between 36-39 degrees and Crystal Clear.
