About Seas Branch

Seas Branch is a small Driftless headwater stream with a strong wild brook trout population — a rarity in southern Wisconsin where brown trout dominate. Cold, spring-fed, technical small water that demands stealth and short rods. Less than ten miles long but a treasured native brook trout refuge.
