Originally known as Llangollen when the town's post office was established on December 4, 1872, its name was later changed to Bloomington. Jennings Randolph Lake to the southwest was completed in 1982 as Bloomington Lake but was renamed in 1987 by the United States Congress for West Virginia Senator William Jennings Randolph.
A proposal has been filed with the Federal Energy Regulatory Commission by Fairlawn Hydroelectric Company to construct a 10.5 MW hydroelectric facility at the Army Corps of Engineers-operated dam for the lake. If approved, construction could occur as early as 2012.
