In the 1930s and 1940s, the idea came up to dam the White River (Arkansas). This was to generate hydroelectric power. The reservoir created by the dam would serve also for flood control on the White River. The dam was authorized under the Flood Control Act of 1941. But World War II and the Korean War delayed construction until 1954. Construction on the Table Rock dam was completed in 1958. It created an impoundment that flooded nearly 79 miles of the White River. It created a lake of over 50,000 acres. Oasis now sits under 100 feet (30m) of water. The church, mill, and other buildings were covered by the lake. The church cemetery was moved to the new Cedar Valley Church on U.S. Route 65.
