Wadi Karkara, Al-Bassa, or Nahal Betsit in Hebrew, is a water current that used to flow continuously and now has intermittent streams and flows. This current is located in the Upper Galilee in the occupied Palestinian territories. Most of the river is located in the nature reserve named after its name, but it is not confined to it, as the water current crosses the border from Lebanon to Galilee, between Sorouh lands, flows towards the west, and drains into the Mediterranean Sea in the south of Ras Al-Naqoura.
