Watershed at a Glance. The Cannon River watershed is located south of the Twin Cities and encompasses areas of Dakota, Goodhue, Le Sueur, Steele, Rice and Waseca counties.

While some large industrial, commercial, and electric generation customers receive natural gas directly from high capacity interstate and intrastate pipelines (usually contracted through natural gas marketing companies), most other users receive natural gas from their local gas utility, also called a local distribution company (LDC).
How Does the Natural Gas Delivery System Work? Gas flowing from higher to lower pressure is the fundamental principle of the natural gas delivery system. The amount of pressure in a pipeline is measured in pounds per square inch.
