'Birkat Ram' is a
crater lake in the northeastern
Golan Heights, near
Mount Hermon. The only sources of the lake are rain water and an underground spring. The water does not leave the lake to any other body of water.
According to The
Talmud, Birkat Ram is one of three underground springs, along with
Hamat Gader in the southeastern Golan Heights and
Hamat in
Tiberias, that opened up in
The Flood of
Noah and didn't close up again after The Flood.
