Sodder is located on the Shuya river, near the western shore of lake Shotozero.
Sodder was established in May 1949. It is named after the ducks living in the area, likely through the Livvi word sotku[2] referring to various species of duck. It was the center of a rural administration including Kamennavolok, Novye Peski and Ulyalega[3] until the 20th of January 2003.[4]
Sodder's economy is based on forestry.[5]
