Fishing forecast (December-March): Brown trout numbers are dense in the Blacksmith Fork River, affecting the size and condition of the fish population in this water. We encourage anglers to harvest brown trout when fishing the Blacksmith Fork. Keeping brown trout will allow the remaining fish to grow to a larger size. Fishing during the winter months can be very good. Spinners, jigs or crankbaits can be used to target trout. Small nymphs of midges, sow bugs, caddisflies and mayflies also work well. Egg patterns used as attractors can also be effective. Streamers in various colors are also a good bet. Ice may form in some reaches of the river, so advanced planning may be necessary for a good trip.
