About this Water
- Freestone
- Best months: Apr–Oct, peak May–June
The Willimantic River in eastern Connecticut is a small-to-medium freestone supporting stocked and holdover trout, with wild brown trout pockets in the upper river. The fishery is accessible and well-known among Connecticut anglers, with the Trout Management Area in Stafford Springs producing the most consistent fishing. Caddis and mayfly hatches through spring and early summer offer the best dry-fly opportunities.
The Willimantic's TMA stretch through Stafford Springs is one of the most-fished trout management areas in Connecticut due to its proximity to Hartford and easy accessibility from I-84.
