Rio Vista, a private water resource located in Payette River, Idaho, is a significant recreational site built in 1971 with a dam height of 20.3 meters and a storage capacity of 41 million cubic meters. Managed by the Idaho Department of Water Resources, this earth dam serves as a popular spot for outdoor enthusiasts seeking activities like fishing and boating on the Hyde Creek and Salmon River. Despite being labeled as having a "significant" hazard potential, the dam's fair condition assessment and controlled spillway with a width of 8 meters ensure safety measures are in place.

With a drainage area of 0.3 square kilometers and a maximum discharge capacity of 118 cubic meters per second, Rio Vista offers an expansive surface area of 11 hectares for recreational use. The dam's structural integrity is regularly inspected, with the last assessment conducted in September 2020. Managed for recreation purposes and with a very high risk assessment rating, Rio Vista remains a vital water resource in Valley County, providing both enjoyment and essential water management functions for the region. As the climate changes and water resources become increasingly important, the sustainable management of sites like Rio Vista will be crucial for ensuring continued access to clean water and recreational opportunities.
