<b>Fishing forecast (December through February):</b> USFS typically closes the upper winter gate in November - anglers are still able to fish the upper reach, near Fifth Water, but you will need to walk in on the road roughly 2-miles from the winter gate parking lot. Diamond Fork Rd, as well as the main day use parking areas, are typically plowed/maintained during the winter. However, snow accumulations in shoulder pull-off areas and non-plowed day-use parking lot areas may require walking some distance to access a desired section of the river. Ice typically starts to accumulate on river features (such as log-jams, woody debris piles, rock structures, etc.) in early December. Subfreezing winter temperatures and snow accumulation can make angler access to the river, as well as wading-walking in the river, challenging and precarious in areas. We advise anglers to use caution and be prepared for winter conditions. Nymphing tends to be one of the more effective and productive winter fly-fishing techniques. We recommend using small (size #18-#20) bead head nymph patterns fished in pockets of slow deep water, as well as fishing midday when temperatures are warmer and the fish are a bit more active.
