The flow providers and constituents of the river are primarily precipitation, groundwater and, to a lesser extent, snowmelt. The river's flow is affected by several dams, including the Wiswall Dam and the Newmarket Dam, which regulate the water levels. Seasonally, the river sees increased flow during the spring and fall, with lower flow during the summer and winter months. The Lamprey River has several tributaries, including the Piscassic River and the Little River. A quirky fact about the river is that it is home to the Lamprey eel, which is an ancient species that has been around since the time of dinosaurs.
