Fishing Conditions in December
Winter is coming…and for us it is already here. Snow has been flying and the temps have been dropping. The holiday season is in full swing and it is a great time to get out on the water. Now granted, fishing access is limited this time of year; but due to the low temps, large swaths of river can be had all to the adventurous fisherman. Just remember to dress in extra warm layers and get some good gloves. Might we recommend the Simms Windstopper Foldover Mitt.
Currently, the best option for getting into some fish is the San Juan river below Navajo dam. Since this is a tailwater, the fishing is always good…if not great. Again, make sure to layer up. If you want the river to yourself, December is the time to fish and in the past few days, streamer fishing has been great.
The Animas, Rio Grand, and upper San Juan are also viable options this time of year. Look for warmer, sunnier days. As the water warms, the fish will become more active so look for a warming trend. Currently it is very cold and fishing can be difficult. With colder water, Trout will seek the deepest part of the river and will rarely move for anything but the most easily accessible meal. They are attempting to conserve their energy. More weight is your friend.
Insects and Natural Food Sources
San Juan – Midges of course! Midge pupa, larva, and adults. Annelids, aquatic worms, eggs, leeches, BWOs.
Animas, Piedra River, and Upper San Juan, Rio Grande – MIDGES! BWO nymphs, sculpins, crayfish, stonefly nymphs. (Fish are going to be seeking deeper water this time of year, so use more weight!)
Los Pinos River – Winter flows. Fishing will be close to impossible
