Home of Missouri River Historical Development, a non-profit agency dedicated to promoting Sioux City and Woodbury County through community grants.
Missouri River Historical Development (MRHD) is the non-profit organization that holds the license for gaming in Woodbury County. Its funding is generated from an agreement between MRHD and Hard Rock Hotel and Casino Sioux City which allows Hard Rock to run a gaming operation in Woodbury County using MRHD’s gaming license.
MRHD was formed in 1989 when Woodbury County voters approved a referendum that sanctioned gaming. A second referendum passed by 75 percent in 2002. The third referendum passed by 77 percent in 2010.
