Upon completion of the Yukarı Gökdere Dam, designed as a clay-cored rock fill dam for irrigation purpose, in Eğirdir district of Isparta, the water started to accumulate in the reservoir. Following this, reservoir’s water level has dropped sharply, and it was completely empty. In the winter season, the dam has accumulated water again; however, two water leakage areas were observed on the downstream side of the dam. Three different survey data were utilized to investigate the seepage paths of the dam. The first data set, before the construction phase, involves the lithological units and rock quality designation indexes in the cores recovered from boreholes, and the in-situ ground water table characteristics and Lugeon’s tests applied in the boreholes. The second data set, electrical resistivity, was collected in three campaigns performed in June 2017, August 2017, and February 2018. Resistivity data were measured using dipole-dipole electrode array with electrode spacing of 1.7 m and 2.5 m in the reservoir, and 3 m on the crest. The last data set includes benchmark readings. With the evaluation of resistivity, geotechnical, and survey data, the leakage in the dam is interpreted to be due to damaged parts in the clay fill material forming the main body of the dam.

在伊斯巴达（Esparta）的埃格迪尔（Eğirdir）地区，为灌溉目的而设计的用作粘土芯石坝的尤卡里（Yukarı）Gökdere大坝竣工后，水开始蓄积在水库中。此后，水库的水位急剧下降，并且已经完全没水了。在冬季，大坝又蓄水了。但是，在大坝的下游发现了两个漏水区域。利用三种不同的调查数据来调查大坝的渗流路径。在施工阶段之前的第一个数据集涉及从钻孔中回收的岩心中的岩性单位和岩石质量指标，以及在钻孔中应用的地下水位特征和Lugeon试验。第二个数据集电阻率 分别在2017年6月，2017年8月和2018年2月进行的三个活动中收集了电阻率。电阻率数据是使用偶极子-偶极电极阵列测量的，电极间距在储层中为1.7 m和2.5 m，在波峰上为3 m。最后一个数据集包括基准读数。通过评估电阻率，岩土工程和勘测数据，可以认为大坝中的泄漏是由于形成大坝主体的粘土填充材料中的损坏部分所致。
