The St. Croix River is a river in northeastern North America, in length,〔U.S. Geological Survey. National Hydrography Dataset high-resolution flowline data. (The National Map ), accessed June 22, 2011〕 that forms part of the Canada – United States border between Maine (U.S.) and New Brunswick (Canada). The river rises in the Chiputneticook Lakes and flows south and southeast, between Calais and St. Stephen. It discharges into Passamaquoddy Bay, in the Bay of Fundy.
==Geography==
The river forms from the Chiputneticook Lakes (North Lake, Grand Lake, Mud Lake, and Spednic Lake) along the Canadian - U.S. border. U.S. Geological Survey topographic maps show the St. Croix River as beginning at the outlet stream from Grand Lake, then flowing through the short Mud Lake and entering Spednic Lake, extending to its outlet at Vanceboro, Maine, and the start of the river proper. Adding the section of river and lake from the outlet of Grand Lake gives a total length of to the St. Croix.〔
The total drainage area of the river is approximately . In the 20th century, the river was heavily developed for hydroelectric power. The river had previously hosted a large population of Atlantic salmon; however, the salmon population was reduced after building hydroelectric dams upriver from Calais-St. Stephen.
The river is an estuary between Calais-St. Stephen and the river's mouth at Robbinston and St. Andrews. This tidal area extends for approximately along this section and exhibits a tidal bore.
