Winter Fishing Update: Big Thompson 

This week brings some cooler temperatures to the area.  Expect quite a bit of ice, but there is some open water near the dam. With high temperatures in the teens this week, small nymphs will be the key to finding success out on the water. We’d recommend a small mayfly or midge rig underneath a yarn indicator in order to detect those delicate strikes and avoid spooking fish.  Be sure to look for deep, slow moving water as fish prefer these holding spots during the winter.  A  pheasant tail or Two-Bit Hooker with a Juju Baetis or BTS nymph trailing behind is a great choice when there is no action happening at the surface.  If you do see a hatch start to come off, Eric's Hi-Vis Midge or Para Midge would be our first choice as a dry fly.  Light tippet (5X-7X) is a must while the water is this clear, and yarn indicators will prevent a lot of missed opportunities.  As always stay safe out there and good luck fishing!
