Connections of a River - Connectivity
Longitudinal disconnects (pg 6 of 9)

Nature occasionally interrupts longitudinal connectivity. Along the North Shore of Lake Superior, for example, the short streams draining from the Lake Superior Highlands evolve according to the general pattern of the River Continuum Concept until they reach the escarpment flanking the lake.

There they speed through dark narrow canyons and plunge over falls more characteristic of the headwater reaches of a stream. The falls block the upstream movement of fish. Such a departure from the pattern of the River Continuum Concept and a return to conditions more typical of upstream reaches is called a reset.
