Tohumluk Creek, one of its main arms, begins in Kurtbeli highland and is used by nomadic people in summers.
Digging in the bed of the stream and pollution from solid wastes of Yağlıdere Municipality have created problems.
According to local history, there was a dairy processing center in Çakrak village of Alucra district.
Because of these waterfalls of tributaries and sharp falls of its main stream on the rocky bed, it appeared as if its surface is covered with a foamy layer of milk and/or cream.
When people in the past viewed the scene formed with foam, they called it "Yağlıdere".
