Editing Mandan, North Dakota (section)

==Economy==
The economy of the surrounding area is largely [[agriculture]]-based. Mandan once had five grain elevators and a flour mill, but none of these remain today. The city continues to support the agricultural industry with livestock sale ring, farm implement dealers and suppliers and finance/lending institutions. But its original purpose was support for the railroad. Subsequent access to rail transportation allowed the agricultural, commercial and industrial sectors to flourish.

In recent decades, Mandan has diversified its economy to include food processing, petroleum refining, electrical power generation, software development, manufacturing and retail trade as well as all manner of professional services for its residents. A federal institution and a women's state prison border the city.

R.M. Heskett Station is an electric generating station operated by Montana-Dakota Utilities Co. along the Missouri River about four miles northeast of downtown Mandan.
