About the Williamson River
The Williamson is a river people fish for one reason, and it is a very good reason. Klamath redband rainbows live in Upper Klamath Lake, grow to extraordinary sizes on the lake’s dense food supply, and then run up the Williamson in summer when the lake warms and its oxygen crashes. Fish of five to ten pounds are the target rather than the exception. They are broad, deep, hard-fighting trout, and they are in a river small enough to cover with a single cast.
The river itself is unusual. It rises in the Klamath Marsh, disappears into porous volcanic ground, and re-emerges downstream from a series of large cold springs, so the lower river below Kirk runs cold and stable even in a hot August. Below Chiloquin it winds through meadow and pine in deep slow bends with undercut banks and heavy weed. Fish hold tight to structure and to the spring inflows. Presentation is slow and deliberate: big nymphs, leeches and streamers worked close to cover, and a dry-fly game during the hatch. Much of the good water is fished from a drift boat or a small pram.
Access is the real constraint and it needs planning. Long stretches of the lower Williamson run through Klamath Tribes land and private ranch ground, and a great deal of the best water is legally reachable only by boat or through an outfitter with permission. This gauge sits near Klamath Agency and reports discharge and stage but no water temperature, which is a genuine limitation on a fishery driven entirely by the temperature difference between the river and the lake. Judge the run by the calendar and by local reports rather than by the gauge alone.

Seasons
Spring: quiet resident trout fishing before the lake fish move, with the river low and clear.
Summer: the run - big redbands push up from Upper Klamath Lake as the lake warms, from about June.
Fall: fish still in the river, cooling water, strong streamer fishing and the fewest boats.
Winter: cold and largely unfished, with limited access and most of the fishery back in the lake.
