Maximum discharge along the river is currently at the Lamoille River At East Georgia reporting a streamflow rate of 459 cfs. This is also the highest stage along the Lamoille River, with a gauge stage of 3.17 ft at this location. This river is monitored from 2 different streamgauging stations along the Lamoille River, the highest being situated at an altitude of 511 ft, the Lamoille River At Johnson.

The Lamoille River is a 85-mile-long tributary of Lake Champlain in Vermont, USA. The river has a rich history that includes being a crucial transportation route for early settlers and playing a significant role in the region's logging industry. Today, the river is used for recreational activities such as fishing, kayaking, and swimming. Additionally, the river is used for farming, including the production of hay, corn, and soybeans. The hydrology of the river is influenced by several dams and reservoirs, including the Green River Reservoir and the Morrisville Dam. These structures provide hydroelectric power, regulate water flows, and support the region's agricultural economy. Overall, the Lamoille River remains an important natural resource for the state of Vermont.

History of the River

The Lamoille River is a river which runs through northern Vermont and drains into Lake Champlain. It is about 85 miles (137 km) in length, and has a drainage area of around 706 square miles (1,830 km2). The river generally flows southwest, and then northwest, from the water divide of the Green Mountains. It is the namesake of Lamoille County, Vermont, through which it flows. The river was the basis of the name of the now-defunct Lamoille Valley Railroad Company, successor to the St. Johnsbury and Lamoille County Railroad.
Legend has it that early French settlers named the river La Mouette, meaning "The Seagull". However, a cartographer forgot to cross the t's, which led people to begin calling it La Moulle. Over time, this became Lamoille, elided in speaking.
