Check out this article on the Jordan River (Jordan River will be dead by next year, environmentalists say)
The article does not contextualize the situation, though. It is an incomplete discussion to talk about the Jordan River without talking about the Israeli occupation of the West Bank and Israel’s crimes throughout the land of Palestine.
From the Palestine Media Center: The headwaters of the Jordan River lie in Lebanon, [the Zionist Entity] and Syria (including the Golan Heights occupied by Israel since 1967). These join to form the Upper Jordan River which flows into Lake Tiberias (also called the Sea of Galilee). After leaving Lake Tiberias, the Lower Jordan River forms the boundary between Israel [The Zionist Entity] and Jordan and then between the Occupied West Bank and Jordan, before flowing into the Dead Sea. There are thus five riparian parties to the Jordan River: Lebanon, Israel, Jordan, Syria and the Occupied West Bank.
Israel withdraws water from the north-western portion of Lake Tiberias and transports it out of the Jordan River Basin through its National Water Carrier to coastal cities and the Negev Desert. The amount of water extracted is such that very little water flows naturally out of Lake Tiberias. This means that only a trickle passes along the West Bank in the bed of the Lower Jordan River. In addition, Israel has denied Palestinians access to the entire Lower Jordan River since 1967. After the start of Israel’s military occupation in 1967, Israel declared West Bank land adjacent to the Jordan River a “closed military zone,” to which only Israeli settler farmers have been permitted access.
I will post additional material when I find the time
