The applicant proposes to excavate approximately 250,000 cubic yards (cys) of sand in Zink Lake. The work would involve the removal of accumulated sediments and rock, and the maintenance of the beaches. This equipment would require bulldozers, scrapers, front-end loaders, and rock trucks.

 

Approximately 9.9 acres (80,000 cys) of sand would be placed in four areas within the Arkansas River

to re-build beaches and to partially fill the existing marina to re-create a portion of the natural ground

that was present when the marina was created.

 

The placement of fill material within the Arkansas River and the method of removing the accumulated

sediment is a "discharge" of dredged material. This includes the addition, placement, or redistribution

of dredged or excavated materials within waters of the United States.

 

The remaining 170,000 cys would be relocated to upland disposal sites that have not been identified by the applicant. The excavation depth of the upstream portion of Zink Dam to 21st Street Bridge is

approximately 4 feet in depth. The maximum depth at Zink Lake Dam would be excavated to 9 feet in

depth near the dam and 1. 7 5 feet in depth near the 21st Street Bridge after the project has been

completed.

 

It is the intent of River Parks Authority, in conjunction with the City of Tulsa, Tulsa County, and PSO,

to relocate sand in order to improve water access for the PSO intake valve.
