In the 1970s, most of the buildings constructed along the shoreline, including the city's marina were abandoned due to rising sea elevation. In the 1980s, the Imperial Irrigation District took proactive water conservation measures to reduce the flow of unused canal water into the Salton Sea. Throughout the 1980s and 1990s, as salinity and suspected pollution levels in the Salton Sea increased, the attraction of the Salton Sea as a recreational destination diminished. Most of the original tourist related structures fell during this time, including the Truckhaven Cafe, the Salton Bay Yacht Club hotel and restaurant, and the Holly House motel and restaurant (later renamed Desser House and then the Sundowner).
