The Potomac Company (spelled variously as Patowmack, Potowmack, Potowmac, and Compony) was created in 1785 to make improvements to the Potomac River and improve its navigability for commerce. The Potomac Company built five skirting canals around the major falls. When completed it allowed boats and rafts to float downstream towards Georgetown, a major port of the time on the Potomac River, now in the District of Columbia. George Washington was its first president, as well as an investor in the company. Tobias Lear, Washington`s personal secretary, was its chairman for a period. Other principals of the company included Thomas Johnson of Maryland.
