“…Depth has reached the maximum value at southeastern part with 7.5 meter however it has fallen into 1.8 meter towards north and west part of the lake. Catchment area is closed by native forest which is consists of the pine trees [28]. Sampling stations provide the well representation of the lake in terms of sedimentation pattern, catchment impacts and human activities.…”

In present study, activity concentrations were indirectly obtained by utilizing alpha spectrometry. Sediment chronology was determined by using modified CRS model. Average sediment accumulation rates are 0.351, 0.324, 0.222 g cm -2 y -1 in S-1, S-2, S-3 stations respectively. With reference to atmospheric 210 Pb flux (29 mBq cm -2 y -1 ) Lake Karagöl has extra outer 210 Pb input (soil erosion) from the catchment area. In terms of Enrichment Factor (EF), heavy metal concentrations are lower than the anthropogenic values. So it can be said that the elements except Au originate from the continental supply. Au has unexpectedly too high level EF value (58.22) in northern station (S-1) of the Lake Karagöl. It corresponds to time interval from 2004 to nowadays. However Pollution Load Index (PLI) says different consequences from the EF values. PLI value has only baseline levels of pollutants in northern part of the Lake Karagöl as it shows progressive deterioration of the site for southern part of the Lake Karagöl.
