## Jail

In 2004–05, a consortium including architectural, bond sellers and contractors located in Texas, promoting the construction of speculative prison and jail ventures convinced Hardin's industrial development authority to float a $27 million bond issuance to build the Two Rivers Detention Facility. It was designed for 464 inmates, and was to be located on a 40-acre (160,000 m$^2$) sugar beet field. The facility was slated to open in July 2007 but the state of Montana would not approve it. The Authority bonds defaulted on May 1, 2008. The consortium's contract terminated in January 2009 without any prisoners ever being housed in the jail.
In November 2009 the Two Rivers Board hired its fifth director. A reserve fund of $814,000 was earmarked to maintain the building for possible future use. It remained complete and vacant for over seven years, though it was partially filled for 18 months. By February 2016, empty once again, it had cost the city $582,595 paid to Two Rivers to maintain it since 2004. Due to unpaid interest on the defaulted bonds, its estimated indebtedness had increased to over $40 million by December 2015.
In April 2019, the Bureau of Indian Affairs took possession and began operations. The name was changed to the Rocky Mountain Regional Detention Facility.
