Mountain Island Hydro Station is a four-unit generating facility with a capacity of 60 megawatts located in Gaston County, North Carolina.

Riverbend Steam Station was a 454 megawatt, coal-fired generating facility located in Gaston County, North Carolina.

Riverbend was used as a cycling station and was brought on line to supplement supply when electricity demand was highest.

Duke Energy claimed that coal ash basins from Riverbend Steam Station has fully been excavated in March 2019.

[1] The North Carolina Department of Environment and Natural Resources is planning a consent order for Duke Energy plants on the lake which have left local groundwater contaminated with high levels of heavy metals such as arsenic and cobalt.

The discharge has come from a lack of lining in older coal ash ponds containing namesake waste which threatens the water quality of Mountain Island Lake's ecosystem and has as of August 2013 warranted over $99,000 worth of fines.

Crescent Land and Timber, a subsidiary of Duke Power, then purchased the property because of its proximity to the Catawba River and the construction of the dam.
