The Sea of Galilee (Hebrew: יָם כִּנֶּרֶת, Judeo-Aramaic: יַמּא דטבריא, גִּנֵּיסַר, Arabic: بحيرة طبريا), Lake Tiberias, Kinneret or Kinnereth, is a freshwater lake in Israel. It is the lowest freshwater lake on Earth and the second-lowest lake in the world (after the Dead Sea, a saltwater lake), at levels between 215 metres (705 ft) and 209 metres (686 ft) below sea level. It is approximately 53 km (33 mi) in circumference, about 21 km (13 mi) long, and 13 km (8.1 mi) wide. Its area is 166.7 km2 (64.4 sq mi) at its fullest, and its maximum depth is approximately 43 m (141 feet). The lake is fed partly by underground springs, although its main source is the Jordan River, which flows through it from north to south.
The Sea of Galilee is situated in northeast Israel, between the Golan Heights and the Galilee region, in the Jordan Rift Valley, the valley caused by the separation of the African and Arabian Plates. Consequently, the area is subject to earthquakes, and in the past, volcanic activity. This is evident from the abundant basalt and other igneous rocks that define the geology of Galilee.
The lake has been called by different names throughout its history, usually depending on the dominant settlement on its shores. With the changing fate of the towns, the lake's name also changed.
Sea of Kinneret
The modern Hebrew name, Kinneret, comes from the Hebrew Bible, the main source of the Christian Old Testament, where it appears as the "sea of Kinneret" in Numbers 34:11 and Joshua 13:27, spelled כנרות "Kinnerot" in Hebrew in Joshua 11:2. This name was also found in the scripts of Ugarit, in the Aqhat Epic. As the name of a city, Kinneret was listed among the "fenced cities" in Joshua 19:35. A persistent, though likely erroneous, popular etymology of the name presumes that the name Kinneret may originate from the Hebrew word kinnor ("harp" or "lyre") in view of the shape of the lake. The scholarly consensus, however, is that the origin of the name lies with the important Bronze and Iron Age city of Kinneret, excavated at Tell el-'Oreimeh. However, there is no evidence that the city of Kinneret itself was not named after the body of water rather than vice versa, or for the origin of the town's name.
Lake of Gennesaret
All Old and New Testament writers use the term "sea" (Hebrew יָם yam, Greek θάλασσα), with the exception of Luke who calls it "the Lake of Gennesaret" (Luke 5:1), from the Greek λίμνη Γεννησαρέτ (limnē Gennēsaret), the "Grecized form of Chinnereth" according to Easton (1897).
Sea of Ginosar
The Babylonian Talmud, as well as Flavius Josephus mention the sea by the name "Sea of Ginosar" after the small fertile plain of Ginosar that lies on its western side. Ginosar is yet another name derived from "Kinneret".
Sea of Galilee, Sea of Tiberias, Lake Tiberias
In the New Testament the term "sea of Galilee" (Greek: θάλασσαν τῆς Γαλιλαίας, thalassan tēs Galilaias) is used in the gospel of Matthew 4:18; 15:29, the gospel of Mark 1:16; 7:31, and in the gospel of John 6:1 as "the sea of Galilee, which is the sea of Tiberias" (θαλάσσης τῆς Γαλιλαίας τῆς Τιβεριάδος, thalassēs tēs Galilaias tēs Tiberiados), the late 1st century CE name. Sea of Tiberias is also the name mentioned in Roman texts and in the Jerusalem Talmud, and was adopted into Arabic as Buhairet Tabariyya (help·info) (بحيرة طبريا), "Lake Tiberias".
Sea of Minya
From the Umayyad through the Mamluk period the lake was known in Arabic as "Bahr al-Minya", the "Sea of Minya", after the Umayyad qasr complex whose ruins are still visible at Khirbat al-Minya. This is the name employed by the medieval Persian and Arab scholars Al-Baladhuri, Al-Tabari and Ibn Kathir.
In 1989, remains of a hunter-gatherer site were found under the water at the southern end. Remains of mud huts were found in Ohalo. Nahal Ein Gev, located about 3 km east of the lake, contains a village from the late Natufian period. The site is considered one of the first permanent human settlements in the world from a time predating the Neolithic revolution.
The Sea of Galilee lies on the ancient Via Maris, which linked Egypt with the northern empires. The Greeks, Hasmoneans, and Romans founded flourishing towns and settlements on the lake including Hippos and Tiberias. The first-century historian Flavius Josephus was so impressed by the area that he wrote, "One may call this place the ambition of Nature"; he also reported a thriving fishing industry at this time, with 230 boats regularly working in the lake. Archaeologists discovered one such boat, nicknamed the Jesus Boat, in 1986.
In the New Testament, much of the ministry of Jesus occurs on the shores of the Sea of Galilee. In those days, there was a continuous ribbon development of settlements and villages around the lake and plenty of trade and ferrying by boat. The Synoptic Gospels of Mark (1:14–20), Matthew (4:18–22), and Luke (5:1–11) describe how Jesus recruited four of his apostles from the shores of the Kinneret: the fishermen Simon and his brother Andrew and the brothers John and James. One of Jesus' famous teaching episodes, the Sermon on the Mount, is supposed to have been given on a hill overlooking the Kinneret. Many of his miracles are also said to have occurred here including his walking on water, calming the storm, the disciples and the miraculous catch of fish, and his feeding five thousand people (in Tabgha). In John's Gospel the sea provides the setting for Jesus' third post-resurrection appearance to his disciples (John 21).
In 135 CE, Bar Kokhba's revolt was put down. The Romans responded by banning all Jews from Jerusalem. The center of Jewish culture and learning shifted to the region of Galilee and the Kinneret, particularly the city of Tiberias. It was in this region that the Jerusalem Talmud was compiled.
The Sea of Galilee's importance declined when the Byzantines lost control and the area was conquered by the Umayyad Caliphate and subsequent Islamic empires. Apart from Tiberias, the major towns and cities in the area were gradually abandoned. The palace Khirbat al-Minya was built by the lake during the reign of the Umayyad caliph al-Walid I (705–715 CE). In 1187, Saladin defeated the armies of the Crusades at the Battle of Hattin, largely because he was able to cut the Crusaders off from the valuable fresh water of the Sea of Galilee.
The lake had little importance within the early Ottoman Empire. Tiberias did see a significant revival of its Jewish community in the 16th century, but had gradually declined, until in 1660 the city was completely destroyed. In the early 18th century, Tiberias was rebuilt by Zahir al-Umar, becoming the center of his rule over Galilee, and seeing also a revival of its Jewish community.
In 1909, Jewish pioneers established the first cooperative farming village (kibbutz), Kvutzat Kinneret in the immediate vicinity of the lake. The settlement trained Jewish immigrants in farming and agriculture. Later, Kvutzat Kinneret pioneers established Kibbutz Degania Alef. The Kvutzat Kinneret is considered the cradle of the kibbutz culture of early Zionism and is the birthplace of Naomi Shemer and the burial site of Rachel—two of the most prominent Israeli poets.
In 1917, the British defeated Ottoman Turkish forces and took control of Palestine, while France took control of Syria. In the carve-up of the Ottoman territories between Britain and France, it was agreed that Britain would retain control of Palestine, while France would control Syria. However, the allies had to fix the border between the Mandatory Palestine and the French Mandate of Syria. The boundary was defined in broad terms by the Franco-British Boundary Agreement of December 1920, which drew it across the middle of the lake. However, the commission established by the 1920 treaty redrew the boundary. The Zionist movement pressured the French and British to assign as many water sources as possible to Mandatory Palestine during the demarcating negotiations. The High Commissioner of Palestine, Herbert Samuel, had sought full control of the Sea of Galilee. The negotiations led to the inclusion into the Palestine territory of the whole Sea of Galilee, both sides of the River Jordan, Lake Hula, Dan spring, and part of the Yarmouk. The final border approved in 1923 followed a 10-meter wide strip along the lake's northeastern shore, cutting the Mandatory Syria (State of Damascus) off from the lake.
The British and French Agreement provided that existing rights over the use of the waters of the river Jordan by the inhabitants of Syria would be maintained; the Government of Syria would have the right to erect a new pier at Semakh on Lake Tiberias or jointly use the existing pier; persons or goods passing between the landing-stage on the Lake of Tiberias and Semakh would not be subject to customs regulations, and the Syrian government would have access to the said landing-stage; the inhabitants of Syria and Lebanon would have the same fishing and navigation rights on Lakes Huleh, Tiberias and River Jordan, while the Government of Palestine would be responsible for policing of lakes.
On May 15, 1948, Syria invaded the newborn State of Israel, capturing territory along the Sea of Galilee. Under the 1949 armistice agreement between Israel and Syria, Syria occupied the northeast shoreline of the Sea of Galilee. The agreement, though, stated that the armistice line was "not to be interpreted as having any relation whatsoever to ultimate territorial arrangements." Syria remained in possession of the lake's northeast shoreline until the 1967 Arab-Israeli war.
In the 1950s, Israel formulated a plan to link the Kinneret with the rest of the country's water infrastructure via the National Water Carrier, in order to supply the water demand of the growing country. The carrier was completed in 1964. The Israeli plan, to which the Arab League opposed its own plan to divert the headwaters of the Jordan River, sparked political and sometimes even armed confrontations over the Jordan River basin.
After 5 years of drought as of 2018[update], Sea of Galilee is expected to get to the black line. The black elevation line is the lowest depth from which irreversible damage begin and no water can be pumped out anymore. Israel Oceanographic and Limnological Research describe it as "The black line marks −214.87 m, the lowest-ever level reached since 1926 when the water level record began. According to the water authority, the Kinneret water level must not decline below this level."
In February 2018, the city of Tiberias requested a desalination plant to treat the water coming from the Sea of Galilee and demanded a new water source for the city. March 2018 was the lowest point in water income[definition needed] to the lake since 1927.
In September 2018 the Israeli energy and water office announced a project to pour desalinated water from the Mediterranean sea into the sea of Galilee using a tunnel. The tunnel is expected to be the largest of its kind done in Israel and will transfer half of the Mediterranean desalted water and will push 300 to 500 million cubic meters of water per year. The plan said to cost five billion shekels. Giora Eiland lead the meetings with the German counterparts to find a suitable contractor to build the project.
In 1986 the Ancient Galilee Boat, also known as the Jesus Boat, was discovered on the north-west shore of the Sea of Galilee during a drought when water levels receded. It is an ancient fishing boat from the 1st century AD, and although there is no evidence directly linking the boat to Jesus and his disciples it nevertheless is an example of the kind of boat Jesus and his disciples, some of whom were fishermen, may have used.
During a routine sonar scan in 2003 (finding published in 2013), archaeologists discovered an enormous conical stone structure. The structure, which has a diameter of around 230 feet (70 m), is made of boulders and stones. The ruins are estimated to be between 2,000 and 12,000 years old, and are about 10 metres (33 ft) underwater. The estimated weight of the monument is over 60,000 tons. Researchers explain that the site resembles early burial sites in Europe and was likely built in the early Bronze Age.
In February 2018, archaeologists discovered seven intact mosaics with Greek inscriptions. One inscription, one of the longest found to date in western Galilee, gives the names of donors and the names and positions of church officials, including Irenaeus. Another mosaic mentions a woman as a donor to the church's construction. This inscription is the first in the region to mention a female donor.
Water use and level
Israel's National Water Carrier, completed in 1964, transports water from the lake to the population centers of Israel, and in the past supplied most of the country's drinking water. Nowadays the lake supplies approximately 10% of Israel's drinking water needs.
In 1964, Syria attempted construction of a Headwater Diversion Plan that would have blocked the flow of water into the Sea of Galilee, sharply reducing the water flow into the lake. This project and Israel's attempt to block these efforts in 1965 were factors which played into regional tensions culminating in the 1967 Six-Day War. During the war, Israel captured the Golan Heights, which contain some of the sources of water for the Sea of Galilee.
Daily monitoring of the Sea of Galilee's water level began in 1969, and the lowest level recorded since then was November 2001, which today constitutes the "black line" of 214.87 meters below sea level (although it is believed the water level had fallen lower than the current black line, during droughts earlier in the 20th century). The Israeli government monitors water levels and publishes the results daily at this web page. The level over the past eight years can be retrieved from that site. Increasing water demand in Israel, Lebanon and Jordan, as well as dry winters, have resulted in stress on the lake and a decreasing water line to dangerously low levels at times. The Sea of Galilee is at risk of becoming irreversibly salinized by the salt water springs under the lake, which are held in check by the weight of the freshwater on top of them.
Up until the mid-2010s, about 400,000,000 cubic metres (1.4×1010 cu ft) of water was pumped through the National Water Carrier each year. Under the terms of the Israel–Jordan peace treaty, Israel also supplies 50,000,000 cubic metres (1.8×109 cu ft) of water annually from the lake to Jordan. In recent years the Israeli government has made extensive investments in water conservation, reclamation and desalination infrastructure in the country. This has allowed it to significantly reduce the amount of water pumped from the lake annually in an effort to restore and improve its ecological environment, as well as respond to some of the most extreme drought conditions in hundreds of years affecting the lake's intake basin since 1998. Therefore, it is expected that in 2016 only about 25,000,000 cubic metres (880,000,000 cu ft) of water will be drawn from the lake for Israeli domestic consumption, a small fraction of the amount typically drawn from the lake over the previous decades.
With extreme drought conditions continuing to intensify, the government of Israel approved a plan in 2018 to pump desalinated water into the lake in an effort to stop the water level from plunging below a point where irreversible ecological damage to the lake might take place.
Tourism around the Sea of Galilee is an important economic branch. Historical and religious sites in the region draw both local and foreign tourists. The Sea of Galilee is an attraction for Christian pilgrims who visit Israel to see the places where Jesus performed miracles according to the New Testament, such as his walking on water, calming the storm and feeding the multitude. Alonzo Ketcham Parker, a nineteenth-century American traveler, called visiting the Sea of Galilee "a 'fifth gospel' which one read devoutly, his heart overflowing with quiet joy".
In April 2011, Israel unveiled a 40-mile (64 km) hiking trail in Galilee for Christian pilgrims, called the "Jesus Trail". It includes a network of footpaths, roads and bicycle paths linking sites central to the lives of Jesus and his disciples. It ends at Capernaum on the shores of the Sea of Galilee, where Jesus expounded his teachings.
Another key attraction is the site where the Sea of Galilee's water flows into the Jordan River, to which thousands of pilgrims from all over the world come to be baptized every year.
Israel's most well-known open water swim race, the Kinneret Crossing, is held every year in September, drawing thousands of open water swimmers to participate in competitive and noncompetitive events.
Tourists also partake in the building of rafts on Lavnun Beach, called Rafsodia. Here many different age groups work together to build a raft with their bare hands and then sail that raft across the sea.
Flora, fauna and ecology
The warm waters of the Sea of Galilee support various flora and fauna, which have supported a significant commercial fishery for more than two millennia. Local flora include various reeds along most of the shoreline as well as phytoplankton. Fauna include zooplankton, benthos and a number of fish species such as Acanthobrama terraesanctae. The Fishing and Agricultural Division of the Ministry of Water and Agriculture of Israel is listing 10 families of fish living in the lake, with a total of 27 species – 19 native and 8 introduced from elsewhere. Local fishermen talk of three[clarification needed] types of fish: "musht" (tilapia), sardine (herring-like), biny (carp-like), and catfish. The tilapia species include the Galilean tilapia (Sarotherodon galilaeus), the blue tilapia (Oreochromis aureus), and the redbelly tilapia (Tilapia zillii). Fish caught commercially include Tristramella simonis and the Galilean tilapia, locally called "St. Peter's fish". In 2005, 300 short tons (270 t) of tilapia were caught by local fishermen. This dropped to 8 short tons (7.3 t) in 2009 due to overfishing.
Low water levels in drought years have stressed the lake's ecology. This may have been aggravated by over-extraction of water for either the National Water Carrier to supply other parts of Israel or, since 1994, for the supply of water to Jordan (see "Water use" section above). Droughts of the early and mid-1990s dried out the marshy northern margin of the lake. A fish species that is unique to the lake, Tristramella sacra, used to spawn in the marsh and has not been seen since the 1990s droughts. Conservationists fear this species may have become extinct. It is hoped that drastic reductions in the amount of water pumped through the National Water Carrier will help restore the lake's ecology over the span of several years. The amount planned to be drawn in 2016 for Israeli domestic water use was expected to be less than 10% of the amount commonly drawn on an annual basis in the decades before the mid-2010s.
