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.
Regulations
Wisconsin Fishing License required ($20 resident + $10 trout/salmon stamp = $30). Season opens first Saturday in May. Verify special-regulation sections in current Wisconsin DNR trout regulations. No USGS gauge — check with regional fly shops before driving.
