About this water

The Situk near Yakutat is Alaska's accessible steelhead river — a short, fishable coastal stream that draws fly anglers north for one of the strongest wild steelhead runs in the state, plus a full house of salmon and Dolly Varden through the year. The spring steelhead run is the headline: bright, hard fish moving through on the river's height and clarity, fished with swung flies and nymphs in the classic way. It's set run_fishery_policy='wild_managed' here because these are native, legally targetable catch-and-release fish, and the brief scores them via the migratory rainbow path. ADF&G's weir count gives a sense of how many fish are in the system, but treat it as context, not a forecast — a high count isn't a bite. Read the river level, mind the Southeast emergency orders, and handle wild steelhead as the prize they are.
