Best time to fish Blacksmith Fork River

The DWR has stocked Blacksmith Fork River 6 times over the last 3 seasons, and 100% of those plants landed in May, June, August — the freshest fish and the easiest bite usually follow within a week or two of a stocking. Flows typically peak in May (about 230 cfs median) and settle to their lowest in January (about 71 cfs) — the wadeable, clear-water window usually opens once flows drop below the seasonal median, and the 72-hour chart above shows where today sits against it.
