Lakes of Israel

The Sea of Galilee — known in Hebrew as the Kinneret, and also called Lake Tiberias, Lake of Gennesaret, Sea of Chinnereth, and Yam Kinneret — is Israel's largest lake and its only natural aboveground freshwater reservoir.[1][2] It lies in the Jordan Rift Valley between the hills of Galilee to the west and the Golan Heights to the east, within the broader East African Rift System.[1] The lake is pear-shaped, measuring 21 kilometres in length and 11 kilometres in width, with a surface area of approximately 166 square kilometres and a maximum depth of 48 metres.[1]

The lake sits well below sea level. Its elevation has been reported at approximately 213 metres below sea level, varying with season and rainfall.[3] Administrative "red lines" are used to manage its water level; the original upper and lower limits, established in the late 1960s, were 208.9 metres and 212 metres below sea level respectively. The lower limit was subsequently reduced several times, and levels below 213 metres can create infrastructure difficulties and affect ecological conditions.[2]

The Jordan River is the lake's primary source of water, entering from the north, flowing through the lake, and continuing southward toward the Dead Sea.[1] Additional inflows come from streams and seasonal watercourses descending from the Galilee hills.[1] Despite being freshwater, the lake's waters are relatively salty, a condition attributed to mineral deposits in the lakebed and strong evaporation.[1] Its watershed covers approximately 2,730 square kilometres, of which about 75 percent lies within Israel and the remainder in Lebanon.[4]

The Kinneret provides roughly 20–30 percent of Israel's freshwater supply and is the country's only natural surface freshwater reservoir among its major water resources. Its average annual renewal rate is approximately 560 million cubic metres.[2][4] In the 1960s it became the starting point of the National Water Carrier — also known as the Kinneret-Negev Conduit — which pumps water northwest from the lake before conveying it through canals, pipes, and reservoirs to Israel's coastal region and south to the Negev.[1][3] Its total capacity has been estimated at 3 billion cubic metres, and it has served as the principal reservoir of that national system.[3]

The Dead Sea is a landlocked, hypersaline lake shared by Israel and Jordan. Its eastern shore belongs to Jordan, the southern part of its western shore falls within Israel, and the northern part of its western shore lies within the West Bank — known by its original, indigenous Jewish name of Judea and Samaria.[5] Nearly all of the lake's water is supplied by the Jordan River, which enters from the north.[5] A 2020 national statistical table includes 265 square kilometres of the Dead Sea, including the southern basin, which functions as an evaporation pond fed from the northern basin.[6]

The Dead Sea is the lowest body of water on Earth's surface.[5][7] Before its level began declining sharply, it measured roughly 80 kilometres long and up to 18 kilometres wide, covering approximately 1,020 square kilometres. The Al-Lisān peninsula divided it into a deep northern basin — as much as 400 metres deep and comprising about three-quarters of the former surface area — and a smaller, shallower southern basin.[5] Its surface elevation stood at roughly 400 metres below sea level in the mid-twentieth century, but by the mid-2010s had fallen to approximately 430 metres below sea level.[5]

Dated sources record the decline at different stages. A country study completed in 1988 recorded an elevation of 399 metres below sea level, while a 2011 report gave 423 metres below sea level.[3][7] The differing figures reflect measurements taken at different times as the water level continued to fall.

The Dead Sea is among the world's saltiest bodies of water, and its extreme salinity excludes most life forms other than specialized bacteria.[7][5] By the twenty-first century, its southern basin had been converted into artificial evaporation pools for commercial salt extraction and had essentially ceased to function as a natural body of water.[5]

Beginning in the 1960s, the diversion of much of the Jordan River's flow by Israel and Jordan for agriculture, combined with commercial use and evaporation ponds, contributed substantially to the decline.[5][7] A 2011 report citing 2010 World Bank data stated that the lake's surface area had fallen from approximately 950 square kilometres in the 1960s to 637 square kilometres in 2007, while its level was falling at about one metre per year.[7] These figures are historical measurements rather than current readings.

Lake Hula was formerly a shallow, pear-shaped freshwater lake in the Hula Valley of Upper Galilee in northeastern Israel, along the Jordan River's course north of the Sea of Galilee.[8] Formed roughly 20,000 years ago, the lake measured approximately 5.3 kilometres in length and 4.4 kilometres in width, covered between 12 and 14 square kilometres, and reached a depth of about 1.5 metres in summer and 3 metres in winter.[8] Together with the surrounding marshes and swamps, the wetland complex covered as much as 60 square kilometres. Papyrus and water lilies grew across the wetlands, which supported water buffalo, wild boar, and migratory birds traveling between Europe and Africa.[8]

The lake was also a site of human settlement and rivalry. The communities of Yesod Hamaala and the kibbutz Hulata, founded in 1934, had a bitter dispute over fishing rights that sometimes escalated into violence and ended in what was described as a "forced truce" when the lake was drained.[9]

In the early 1950s, Israeli authorities decided to drain the lake and surrounding wetlands to expand agricultural land and eradicate malaria in the Upper Galilee.[9][8] Scientists and nature advocates objected, warning that the peat soil would sink and become unsuitable for farming. The phrase "Zionist peat does not sink," mistakenly attributed to Ben-Gurion, became associated with the dispute.[9] On 6 June 1956, it was decided to turn part of the dried lake area into a nature reserve.[9] A preserved 350-hectare area of papyrus swamp formally became Israel's first nature reserve in 1963.[8]

The Jewish National Fund carried out the drainage operations between 1951 and 1958, and the project added approximately 5,000 hectares of arable land.[8] The ecological losses were severe: 119 animal species disappeared from the region, 37 of them entirely from Israel.[8] Among the lost species was the Hula painted frog, which was long considered extinct.[10]

By the 1980s and early 1990s, peat degradation, subsidence, underground fires, dust storms, and winter flooding had made cultivation difficult or unprofitable in increasing portions of the reclaimed land.[8] In the post-drainage landscape, the Jordan River continued through the drained Hula Basin toward Lake Tiberias, leaving the basin as an altered landform rather than an extant lake.[3]

Ecological deterioration in the drained Hula Basin prompted a restoration effort that culminated in the creation of Lake Agmon in the 1990s. The restoration project commenced in 1993, and between 1993 and 1998 the Jewish National Fund invested approximately 70 million NIS in rehabilitating the peatlands.[8][11] Lake Agmon was dug in peatland considered poorly suited to continued agriculture and was flooded in April–May 1994.[8] The broader wetland rehabilitation redirected freshwater through dams and pipes,[10] while the Agmon project was designed to stabilize groundwater, reduce pollution flowing toward the Kinneret, and support ecotourism.[4]

Lake Agmon is not a recreation of historic Lake Hula. It is smaller and shallower, covering approximately one square kilometre and reaching depths mostly below one metre.[8] Its water comes principally from the Jordan River and a canal carrying peat drainage water, and the water is unsuitable for drinking.[8] The marshy lake contains about one million cubic metres of water, with channels and an irrigation pumping system used to maintain wet soil and green areas.[11]

The ecological recovery following reflooding has been notable. More than 30 aquatic plant species re-established spontaneously in and around the lake during its first years after flooding.[8] At least 120 bird species were recorded in or around Lake Agmon within its first three years, including migratory pelicans, storks, cormorants, and cranes, which use the area as a feeding station on routes between Europe and Africa.[8] Small islands within the lake were designed as protected nesting sites.[8] A 2007 account reported approximately 40,000 cranes in the Hula Valley during the peak migration season and described Agmon Hula as a major attraction for birdwatchers.[12] Following improved water quality and habitat restoration, the Hula painted frog — once considered extinct — was rediscovered in the valley.[10]

Birkat Ram, also called Ram Pool or Lake Ram, is a small natural lake in the northeastern Golan Heights, near the Druze communities of Mas'ade and Majdal Shams.[13] It occupies a basanitic maar, a volcanic crater that currently hosts the lake.[14] It is described as the only natural lake of its kind in the Golan Heights.[13] Its dimensions are approximately 850 metres in length and 600 metres in width, with a water depth of 6 to 10 metres and an elevation of 950 metres above sea level.[13] Its formation was probably associated with an ancient volcanic eruption.[13]

The maar contains approximately 90 metres of lake sediments, with radiocarbon ages extrapolated to around 108,000 years at the base of the sediment sequence, making it a record of the region's geological past.[14] Local Druze fishermen catch fish in the lake, which has also been used in summer for swimming and picnicking.[15] Birkat Ram is located in the Golan Heights, a territory whose political status is contested, and its geographic identification does not resolve sovereignty questions.

Beyond the country's major water bodies, Israel contains several smaller lakes of natural, artificial, or accidental origin distributed across diverse landscapes.

Lake Yiron, also described as Yiron Living Lake, is a natural lake fed by spring water in the center of Kibbutz Yiron in the Upper Galilee.[13] A wildlife rehabilitation area surrounds the lake, and visitors can hire pedal boats to travel among the waterfowl that inhabit its waters.[13]

Lake Nitzanim formed when a kurkar — fossilized coastal sandstone — quarry near Nitzanim Beach on the Mediterranean coast was flooded by rising groundwater.[13] The quarry had been worked in connection with road-widening projects on Highway 4 and the Ayalon Freeway. Operations stopped after workers discovered the flooding, and a two-part lake formed, connected by a 1.5-kilometre waterway.[13]

In the coastal city of Rishon LeZion, two adjacent water bodies sit among the sandy terrain: the Superland Lagoon and Nakik Lake.[13] The Superland Lagoon formed in winter 1992 during heavy rain combined with excavation, after which the local water corporation maintained it by adding urban runoff.[13] Nakik Lake formed in the same year; pumps beside it draw water from the Superland Lagoon when flooding threatens.[13] The pair function as an urban nature and birdwatching area, although swimming and entering the water are prohibited.[13]

In the Beit She'an Valley, the Huga Springs feed a park containing three interconnected lakes through which spring water flows continuously.[13] The setting includes shaded lawns and picnic areas, although individual lake names and dimensions are not recorded in the source.[13]

Lake Monfort — also called Lake Ma'alot and formerly known as the Hosen Reservoir — is an artificial lake at the lowest point of Ma'alot-Tarshiha in northern Israel.[16] A 350-dunam park developed around it includes a promenade, sculptures, pedal boats, and other recreational facilities.[16]

Sapir Lake is a small water body in the central Arava desert, located within Sapir Park.[13] Two springs in the park feed a small waterfall that flows into the lake, which supports fish, ducks, and other waterfowl.[13] Whether the lake is natural or artificial is not established in the available source.[13]

A 2020 national statistical table lists two entries under its "area of lakes" category: the Sea of Galilee at 164 square kilometres and the Dead Sea at 265 square kilometres, for a combined total of 429 square kilometres.[6] The Dead Sea figure includes its southern basin, identified in a footnote as an evaporation pond fed artificially from the northern basin rather than a functioning natural lake.[6]

The Sea of Galilee occupies a uniquely central place in Israel's water economy as the country's only natural aboveground reservoir among its major water sources.[2] Its average annual renewal rate is approximately 560 million cubic metres.[2] Its 2,730-square-kilometre watershed is partly shared with Lebanon.[4] The lake became the source of the National Water Carrier, the engineering system that has distributed freshwater to Israel's populated coastal plain and the Negev since the 1960s.[1]

The Dead Sea's place in Israel's statistics is complicated by its transboundary nature and accelerating decline. Its surface area, once approximately 1,020 square kilometres, had fallen to a reported 637 square kilometres by 2007, while its level was falling at about one metre per year.[5][7] The conversion of its southern basin into evaporation ponds means that less than the full statistically recorded area functions as a natural lake.[6][5]

Historic Lake Hula, though no longer an extant natural lake, continues to shape Israel's hydrology and conservation policy. Its drainage altered the Jordan River's natural route through the Hula Basin, while the subsequent restoration created Lake Agmon as a functioning wetland designed partly to reduce pollution inputs into the Kinneret downstream.[4] Birkat Ram and the smaller lakes described above fall outside the table's formal accounting but remain components of Israel's broader hydrological and ecological landscape.[6]

Several water bodies listed here involve complex territorial questions. The Dead Sea's eastern shore belongs to Jordan, its southern western shore lies in Israel, and its northern western shore lies within Judea and Samaria.[5] The inclusion of part of the Dead Sea in Israel's national lake-area data does not imply that the entire lake lies within Israel.[6]

Birkat Ram is located in the Golan Heights, whose sovereignty remains contested. Its inclusion here reflects its geographic location and present administrative context without resolving that broader dispute.[14][15]

The drainage of Lake Hula is also debated as an example of the tradeoffs between agricultural development and ecological preservation. Although the project added arable land, peat degradation and the loss of at least 119 animal species from the region later helped prompt wetland restoration.[8]
