Lamoille River

About

Lamoille River, Vermont — 1812 Smugglers' Notch, Prohibition. Long before Euro-American contact, the Lamoille River valley served as an important Western Abenaki travel corridor connecting the Green Mountains to Lake Champlain. Abenaki habitation was extensive across the 1700s through 1840s. The river's name may derive from the French 'la mouette,' meaning seagull — a small linguistic clue to the layered history of the valley.

The War of 1812 marked the first Euro-American event to leave a lasting name on the landscape. Smuggler's Notch earned its title because smugglers used the rugged path through the mountains to move supplies to and from Canada during the war, when official trade was forbidden. The secluded caves along the pass were well suited for storing contraband, and the notch remained a hotspot for smuggling activity up to and through the conflict. That defiant geography still shapes the valley's character today, and Smuggler's Notch endures as a principal destination for hiking and sightseeing in the Green Mountains region.

From the 1830s through the 1920s, the Lamoille watershed was logged to support the regional timber industry of the 1850s–1910s and the railroad expansion of the 1860s–1910s. Local sawmills, logging drives, and downstream lumber operations were the major operators. The exhaustion of the old-growth stands around 1910, the start of state forestry conservation in 1915, and the establishment of state forests in the 1930s together brought large-scale logging to an end. Industry left other marks as well: the Belvidere Mountain asbestos mine operated from 1908 to 1979, and the 1920s Prohibition era added another chapter to the corridor's long association with contraband and enforcement.

Hydrological study of the river began early. USGS surveys in the 1870s–1890s, gauging-station establishment in the 1880s–1910s, and state geological streamflow assessments in the 1910s–1930s formed the first comprehensive studies of the Lamoille. State water-pollution-control studies in the 1950s–1970s and Clean Water Act assessments from 1972 to 2000 addressed more than a century of logging, agricultural, and industrial impacts. In August 2011, Tropical Storm Irene caused catastrophic flooding on the Lamoille and nearly every Vermont river, destroying bridges and roads, reshaping channels, and prompting major statewide investment in flood resilience.

The modern era belongs to restoration. Between 2010 and 2024, the Lamoille became the setting for one of the largest dam-removal and river-restoration efforts in Vermont history, a sustained campaign to reopen the waterway and revive its natural flow. Over the same span, Lamoille conservation work protected 80 percent of the watershed from development. The effort has paid off in the water itself: the Lamoille endures as a premier brook trout and landlocked salmon fishery, drawing anglers to its cold, clear runs. For paddlers, the river runs Class I–III, from the Class I–II mountain valley between Morrisville and Johnson to the Class II–III Fairfax Gorge between Johnson and Fairfax. Managed under the Vermont Rivers Management Program with headwaters in the Green Mountain National Forest, the Lamoille remains a principal destination for canoeing, kayaking, and whitewater rafting in northern Vermont.
