In addition to Ceyhan-Aslantaş Scoping and Case Studies, in December 1999, WCD requested AGRIN to conduct Cross-Check Surveys in order to check the general status of the Ceyhan River Basin. For this purpose three surveys were carried out for two dams in the upper Ceyhan Basin and for Aslantaş Dam. With the crossc-check survey Sir, Menzelet and Aslantaş Dams were questioned on projected and actual base.
