Lower Provo 100 CFS
Winter has finally settled in and it’s time to adjust your focus for some Utah winter fly fishing. Time to go with a lighter nymph rig, meaning smaller weights, smaller indicators and smaller tippet. Dry fly rods should be a 3 or 4wt. with 6x or even 7x tippet. The main winter hatch are the midges and they are small in the 20-24 range. The fish’s metabolism slows way down so the strikes are very light and any movement on an indicator should have you doing a light lift on the rod tip to check. These conditions should stick around till mid-March. The Lower Provo stays in the shade a long time in the morning and fly fishing really doesn’t get going till after 11 am. The sunny calm days with temperatures in the 30’s will produce the best midge hatches. As the moss is breaking up we will see a lot of sow bugs and scuds in the drift. These are a major source of food for the trout in winter and you should carry a good supply in a variety of sizes and colors. The fish are beginning to move into the deeper pools where it is much easier for them to control their body temperature and expend the least amount of energy possible.
Middle Provo 130-150 CFS
Like the Lower Provo the Middle is into that winter mode. The Heber Valley is prone to the inversion during the steady barometer high pressure days. Better to get down to the river after it has warmed up a bit. Good midge hatches happen around mid-day and the fish can be quite aggressive on the dry fly takes. Nymphing with small midge patterns is the norm. Size 20-24 in a variety of colors. As the winter moves on the hatches will only get more intense and spread out with the warmer days in the 30’s being the best. Right now you may have to do a little hunting. If you are not seeing midges by noon start walking the banks. Some pools and flats will have very good hatches while others are quite sparce. If it is a very cold day you may have to move up closer to the dam to see midges. Look for fish suspended in the water column. In winter the fish like to feed on the midge pupa as they make their way to the surface. Fly fishing a midge pupa pattern in the surface film with a little frog’s fanny on it is a great way to go. Things all but shut down by a little after 3pm.
Weber River 24 CFS
The Weber is still at very low levels and now with the cold weather the ice shelves are beginning to form. You will need a lot of patience to fish the Weber this winter. Decent drifts are almost non-existent at these levels. White fish are spawning so look for trout behind the redds.
