The St. Lawrence River is a very large river ecosystem. In such systems, the relationships between aquatic communities and nutrients may be confounded by physical factors that exert their influence temporally and spatially at the local scale, as well as along a .

In the late 19th century, the transportation needs of Quebec led to proposals for bridging the St. Lawrence River. The Quebec Bridge was the longest cantilever structure attempted until that time. In its final design, the clear span was m (1, ft) long. .   These economic, environmental, and social criteria represent an unprecedented expansion of inquiry related to water regulation in the basin. Although not exhaustive (as discussed later in this report), the LOSLR scope extends far beyond the historical preference given to domestic water use, navigation, hydropower, and irrigation (Boundary Waters Treaty, , Article VIII).

Lake Michigan Diversion Accounting Information Web site The diversion of water from the Lake Michigan watershed is of major importance to the Great Lakes states and to the Canadian province of Ontario. The objective of this study was: (1) to investigate the diagenetic changes in the lipids with depth in the sediments, and, (2) evaluate the relative contribution of marine and terrestrial organic matter in the sediments of the St. Lawrence estuary. The freshwater from the St. Lawrence river transports the untreated municipal sewage and the.
