Syndle (historic: "Søndlevatn") is a lake in the municipality of Grimstad in Agder county, Norway. It is located in the Landvik area, about northwest of the center of the town of Grimstad. The 6km2 lake Syndle flows into a small river on the northeast part of the lake which connects it to the neighboring lake Rore which eventually flows into the river Nidelva.[1] [2]
