🏆 National Wild & Scenic River — Pristine river corridor on the Eightmile River — one of only 2 National Wild & Scenic Rivers in CT
Eightmile River Wildlife Management Area protects habitat along the Eightmile River — one of only two rivers in Connecticut designated as a National Wild and Scenic River. The river and its tributaries drain a remarkably undeveloped 62-square-mile watershed in the southeastern Connecticut hills. The pristine water quality supports native brook trout, river otter, and bald eagles — a testament to the watershed’s health.

Frequently Asked Questions
Can I fish for brook trout?
The Eightmile River supports wild, native brook trout — a sign of exceptional water quality. CT fishing license required. This is catch-and-release fly fishing at its best in southern New England.
What does Wild and Scenic mean?
The Wild and Scenic Rivers Act (1968) protects rivers with outstanding natural, cultural, or recreational values — preventing damming and limiting development within the corridor. Only 0.25% of US rivers have this designation (compared to 25% that are dammed). The Eightmile River earned designation in 2008 — one of very few in the urbanized Northeast. The designation preserves the river’s free-flowing character while allowing continued private land ownership.
About Eightmile River
Eightmile River Wildlife Management Area protects land along the Eightmile River — one of only 14 rivers in the United States designated as a National Wild and Scenic River in its entirety. The river runs through one of the most intact forest landscapes in southern New England, with clean water supporting native brook trout populations.
Things to Do
Fishing for native brook trout (one of the few remaining wild populations in Connecticut), hunting (seasonal), hiking, and birdwatching. The river’s pristine condition and Wild and Scenic designation make it ecologically significant.
Insider Tips
Wild and Scenic: The Eightmile River is CT’s only federally designated Wild and Scenic River — recognized for its exceptional natural and scenic values. Pro tip: The Eightmile watershed is one of the least-disturbed watersheds in southern New England — supporting native brook trout and rare freshwater mussels. Community effort: Local residents drove the Wild and Scenic designation — a grassroots conservation success.
Best Time to Visit
Spring: High water and wildflowers. Fall: River valley foliage. Summer: Swimming holes. Winter: Quiet forest trails.
Wildlife & Nature
Cromwell Meadows preserves one of the finest remaining Connecticut River floodplain meadows — grasslands that flood annually when the river rises, depositing nutrient-rich sediment. These meadows support grassland bird species that have declined dramatically across New England — bobolinks, Eastern meadowlarks, and savannah sparrows all nest here. The annual flooding prevents forest succession, maintaining the open grassland character without human intervention. American kestrels — North America’s smallest falcon — hunt the meadows for grasshoppers and voles. The floodplain’s rich soils support Connecticut River shade tobacco — a unique crop grown under cheesecloth canopies for cigar wrappers, once the most valuable crop per acre in America.
Nearby Attractions
Dinosaur State Park in Rocky Hill preserves 500+ dinosaur tracks from 200 million years ago — visitors can make plaster casts of actual tracks. Wangunk Meadows across the river offers additional floodplain birding. Middletown is home to Wesleyan University — known for its arts programs and progressive culture. Arrigoni Bridge (1938) — an Art Deco steel arch bridge — connects Portland to Middletown with dramatic views of the Connecticut River valley. Brownstone Quarries in Portland once supplied the distinctive brown sandstone that defines New York City’s iconic brownstone rowhouses.
