In 1952, Lake Eucha in Delaware County, Oklahoma, was created by completion of the Eucha dam on Spavinaw Creek. This lake is owned by the City of Tulsa, Oklahoma and functions as additional storage and as a buffer for Lake Spavinaw, which is the principal municipal water source for Tulsa. The lake is 13.7 km long by 1.1 km wide. with a storage capacity of 99,000,000 m3. Its surface area is 11 km2 and the shoreline is about 80 km. The Cherokee community of Eucha, Oklahoma was relocated to higher ground before the dam was constructed, because the lake waters were to submerge the original townsite. Lake Eucha is also a popular place for fishing.
