Experience Premier Fly Fishing

Welcome to Yamsi Fly Fishing — where quiet water, wild trout, and true solitude define the experience.

Located at the headwaters of the legendary Williamson River, Yamsi Fly Fishing offers something rare in today’s world: six miles of private river in the heart of Oregon’s high country. Here, the river begins — clear, slow-moving, and full of life — winding through open meadows beneath the watch of Yamsay Mountain.

Our water is intimate and unhurried. Broad, gentle currents glide through weed beds and glassy channels where native redband trout and brook trout cruise and feed.  At Yamsi Fly Fishing, the river doesn’t rush — and neither do we.

Come experience private water.

Come fish where the Williamson begins.

Come discover fly fishing the way it was meant to be.
