About Mt. Vernon Creek

Mt. Vernon Creek south of Madison is a productive Driftless spring creek in Dane County — small, cold, and rich with wild brown trout. The stream flows through a mix of pasture and hardwood, with public-access easements along most of the trout water. A classic Driftless dry-fly destination during the Sulphur and Trico hatches.
