Lake Eucha

In 1952, Lake Eucha in Delaware County, Oklahoma, was created by completion of the Eucha dam on Spavinaw Creek. The nearest town is Jay, Oklahoma. 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.

Description
The lake is 8.5 miles long by 0.7 mi wide. with a storage capacity of 80,000 acre.ft. Its surface area is 2,800 acres and the shoreline is about 50 mi.The dam elevation is 778 ft and is 2,100 ft long.

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.

W. R. Holway is credited with the design and construction of both projects.
