REACH Museum, Museum and visitor center in Richland, United States

The REACH Museum is a museum facility in Richland dedicated to the history and science of the Columbia Basin region. The building and grounds feature interactive exhibits about Ice Age floods, settlement patterns, and regional infrastructure development.

The museum was established in 2014, evolving from the Columbia River Exhibition of History, Science, and Technology to document the region's transformation during the Manhattan Project era. This project fundamentally altered the area's economy and population.

The museum's name comes from the Hanford Reach, the last free-flowing stretch of the Columbia River in the United States. Gallery two covers the Hanford Site's early days and its role in the Manhattan Project, while a rotating gallery presents changing local history stories. An outdoor stage hosts events and musical performances.

The grounds can be explored on foot, with walking paths leading through outdoor exhibits and gardens that accommodate different mobility levels. It helps to wear comfortable shoes and allow time for exploring the interactive content both indoors and across the open spaces.

The grounds feature art installations and sculptures that illustrate the story of water management and irrigation projects that shaped the region. These physical elements show how human intervention transformed the landscape and the role water played in regional development.
