Hello Ike,
Your first photo in the WS shows how green this area has become.
I'm always amazed at the presence of water in a desert. I once saw a small oasis with a year round pond in the middle of a sandy desert in western China.
I understand that a dam has created the lake here. But from where comes the water of Revivim Creek? Is there a period of heavy rainfall in the Negev desert?
The slopes in the background give me the impression that a drop of water never falls.
BTW, were the frogs ever brought in from elsewhere? Or do they find their way to the lake by themselves. I apologise for the many questions.
Best regards, Paul

To PaulVDV: Flood water
Good morning Paul,
Good questions you posted. In the Negev desert, flood waters mostly remain on upper level of the ground, the soil is not permeable, thereafter become floods. It does rain for little known times, and water accumulate in lower terrain. As for the frogs, and the fishs there - most probably brought by humen sometimes ago. Have a nice new week, Ike
