What is "satraan"

Sätraån ( Swedish: "Stream of Sätra") is a stream in southern Stockholm, Sweden.

Previously stretching 6 km from Västertorp and Segeltorp, Sätraån is today confined to the Sätra Open-air Area and approximately a kilometre long. The limited current discharge causes the stream to be reduced to minor temporary pools of water except during spring. Nevertheless, the stream is considered a valuable natural environment because of the ravine it has cut though the landscape and because of its location in a forest of recreational importance to the suburb Sätra.
