              HYDROTECHNICAL HERITAGE OF  VOJVODINA AND ITS POTENTIALS
                Less Known Face of the Plain
                They were endless marshes and brought many troubles. A boundless  puddle which sometimes threatened to swallow everything. Efforts to make canals  for draining surpluses of water, dry the marsh and turn it into granaries began  in the XVIII century. The construction of the 110 kilometers long Big Canal of  Bačka began already in 1793. Last year observed sixty years since the beginning  of the Danube-Tisa-Danube hydrosystem construction. Today it is a network of  natural and artificial water streams, almost a thousand kilometers long,  thereof 600 navigable. There are 86 bridges on it, many locks, dams, pumping  stations… A real treasure waiting to be utilized better

Today a  granary, a boundless sea of farmland, Vojvodina looked completely different in the  not such distant past. In the early XVIII Century, when the last Turkish  conquerors were leaving those lands, the Danube, Tisa, Begej, Tamiš, Brzava and  other watercourses flowed into endless ponds and marshes, bringing only  troubles to rare inhabitants. Epidemics ravaged, rare and low quality roads  were flooded, and the development of agriculture couldn’t even be imagined.
                During  the great people’s migration to the then Austro-Hungarian territory, when Serbs  under Čarnojević, Germans, Slovaks, Rusines, Romanians began arriving north of  the Sava and the Danube, the first ideas and plans about drying marshes and  turning them into farmland appeared. Finally, in 1793, under management of  hydrotechnical engineer Joseph Kish (Budapest 1748, – Sombor, 1813), works on  the construction of the Big Canal of Bačka commenced, from Bezdan on the Danube  to Bečej on the Tisa. With a total length of 110 kilometers, the canal they  also call Kish’s is today the central part of the powerful Danube-Tisa-Danube  hydrosystem.
                
Based  on the achievement of Joseph Kish, author, architect and first builder of the  canal, other segments of this hydrosystem, the biggest hydrotechnical endeavor  in the middle Danube area, on a terrain with particularly complex hydro-geographical  features, were realized later. The Big Canal of Bačka was dug manually, hiring  up to two thousand workers, and was put into operation in 1802. Its builder,  following his own wish, was buried on his estate in Vrbas, on a hill  overlooking the canal, Kish’ life’s work.
                A  memorial was raised in the immediate vicinity of the Vrbas Šlajz, one of the  most important hydrotechnical objects on the canal route. Šlajz in Vrbas  originates from the time of building the Big Canal, with characteristic oak  gates and shackles hammered in Austria, while the lock was built of brick.  During the Danube-Tisa-Danube hydrosystem construction in 1967, it was  reconstructed and adapted in accordance with then technical requests. Today  this area is a city resort and place for resting, recreation, sports and  fishing.
                Locks,  dams, pump stations and accompanying equipment are part of the rich  hydrotechnical heritage of Vojvodina and direct testimony of transforming  swamps and flooded areas into farmland and wheat fields. 
              DAMS WHICH CONNECT
              
Thanks to the Big Canal of Bačka, as well as  other canals in this hydrosystem, many places throughout Vojvodina got their ”rivers”:  Sombor, Vrbas, Kula, Crvenka, Srbobran, many smaller towns. In time, people got  used to living next to the canals, using all their possibilities and  advantages. The Big Canal of Bačka enters the Tisa near Bečej at its end, where  nature was especially generous and rich in flora and fauna. Another object,  which also became a valuable part of the hydrotechnical heritage, was built  here, a dam, both visually and functionally interesting. It is believed that it  was designed in the famous studio of Gustave Eifel, who participated in  building different steel constructions throughout the Austro-Hungarian Monarchy  at the time. It was the first lock in Europe powered by self-produced direct  current, from a turbine built on the right bank of the Tisa, immediately next  to the canal. It was strong enough to set the šlajz in motion during opening  and closing, as well as a big sawmill. When the dam was completed, in 1896, it  was a ”technical wonder” for the time. People say that almost all reputable  European hydrotechnology engineers were present at the opening, as well as two  engineers from Japan.
                
Out of operation since 1975, it  was proclaimed a cultural monument. Today it serves only as a sluice gate  during declined water levels of the Tisa. The Bečej šlajz, a place often  visited by locals, is also attractive to artists, especially filmmakers.
                The sluice near Klek, a  settlement near Zrenjanin, was built immediately before World War I, at the  time of canaling waters in Banat, in this case the river Begej, from its  confluence into the Tisa to Timisoara in Romania. With a role to maintain the  water level in the river during low and medium flows, this sluice also  represents an interesting engineering and architectural work. A lock with one  ship chamber was built next to it. The sluice was upgraded in 1969, within the  extensive investments in the canals and objects of the Danube-Tisa-Danube  hydrosystem, and enables passage for ships up to 500 tons. Identical to the one  in Klek, the sluice in Srpski Itebej was built in the same period, near the  Serbian-Romanian border, about twenty kilometers upstream. 
              POSSIBILITIES  AND EXPECTATIONS
              Hydrotechnical  objects on canals were built to regulate different inflows of water from big  rivers, accept surpluses of water during floods if necessary, or, irrigate the  surrounding land in dry seasons by pumps. When the idea about constructing the  Danube-Tisa-Danube canal network was initiated in 1947, the five existing locks  of the Canal of Bačka were connected to the hydrosystem, and ten new built  along its route. The Danube-Tisa-Danube hydrosystem, with natural and partially  reconstructed watercourses, is almost a thousand kilometers long, thereof 600  kilometers navigable. Its network connects as many as 80 settlements in  Vojvodina. Since many roads were cut by digging the canal, 86 concrete bridges  were built – for road vehicles, railway and pedestrian.
                The previous year, 2017, was thus a year of a  triple jubilee – 70 years since the idea about the construction, 60 years since  the commencement of building (1957) and 40 since the completion, when (in  1977), the largest object in the hydrosystem, the dam on the Tisa near Novi  Bečej, was put into operation. From that dam, a network of watercourses through  Banat is connected to the Big Canal of Bačka, until they meet again with the  Danube near Banatska Palanka. The mighty river, before its entrance into the  Đerdap Gorge, under the medieval Ram fortress on its right bank, proves is  power once again, reminding of a large lake with its width.
                
Miodrag Zarić in Čenta, a village located in  the middle of the road between Belgrade and Zrenjanin, gave a unique example of  the revitalization of hydrotechnical heritage and its adaptation to elite  tourism. The famous businessman and founder of the Special Hospital for  Hyperbaric Medicine not only completely renewed the old pump station from 1909  at his estate, used for draining surpluses of water from the Danube and Tisa  marsh, but also complemented the estate with 12 apartments in the Banat  ethno-style, a restaurant, mini zoo, sports and recreation grounds. After six  years of regaining its previous splendor, the desolated and forgotten pump  station with powerful steam engines thus became an integral part of a unique  eating establishment, together with a white ”Steinway” piano, ownership of the famous Serbian painter Paja  Jovanović in 1934...
                Thanks  to the canal network and numerous hydrotechnical objects on it, the people of  Vojvodina gained a great fortune, although it seems it is insufficiently  utilized. Development of agriculture, irrigation and drainage, transportation  of goods, recreational sailing, tourism, fishing, improvement of river banks,  all this can be much more developed than it is the case now. Serbia opens many  of its doors to the world, but perhaps it would be easiest and fastest to open  the water gates, revitalize sluices and locks on rivers and canals, and greet  smaller and bigger ships and boats from neighboring and other European  countries in a more serious manner. And offer them resting and enjoying the  undiscovered part of the plain…

              Šlajz
                Ship  locks on canals, whose German name schleis has been used to the very day, were  places where locals liked to gather. They are arranged areas of river banks,  attractive for picnics, somewhere also for bathing. They are especially loved  by fishermen, since schools of fish are retained before sluices and there are  much more of them than in other parts of the watercourses.

              Hydro-Knot  in Klek
                Also  known as Šlajz, the hydro-knot in Klek is an arranged local resort, with tied  small ships, nice hidden places for fishing, a place where the youngest can  hear and see a waterfall, even in the middle of the plain. Only a few hundred  meters downstream, the Begej canal merges with the original river course, and  somewhat further – the people of Klek call the place the Triangle – the route  of the Danube-Tisa-Danube Canal separates from the river towards the village of  Botoš, where it merges with another important watercourse of Banat, the Tamiš.
