The regulations are a bit complicated, so be sure to read them thoroughly.

If the weather is warm enough for there to be moving water in the Box Canyon, try streamers and nymphs there. Small beadhead nymphs--in the size 18-20 range--are effective. You may need to team that fly with a large nymph, such as a Kaufmanns Stonefly, or with some split shot in order to reach the trout's level.

The remainder of the ranch section closes November 30 (part of it closed September 30). During cold weather, it's possible for the slow moving Ranch water to freeze. If the water is not in a solid form, you can expect some size 22-24 blue-winged olives early in the month, and midges the rest of the time. Afternoons will be best, although some hatches can continue until dusk.

When fishing the Box Canyon and the Ranch water, remember that the weather is about 20 degrees cooler in Last Chance than it is in Ashton and St. Anthony.

The river is open all year between the Warm River confluence and Ashton Dam, and downstream from Vernon Bridge (check the regs for details). Midges, some blue-winged olives, and streamers are most effective in this water.
