In 1952, Lake Eucha in Delaware County, Oklahoma, was created by completion of the Eucha dam on Spavinaw Creek.[1] The nearest town is Jay, Oklahoma.[2] 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 8.5miles long by 0.7miles wide. with a storage capacity of 80000acre.ft. Its surface area is 2800acres and the shoreline is about 50miles.The dam elevation is 778feet and is 2100feet long.[3]
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.[4]
Lake Eucha is also a popular place for fishing.
W. R. Holway is credited with the design and construction of both projects.[5]
