Bartoszowice Barrage is a barrage in Wrocà Âaw, one of the structures of the , located on its main waterway running through the city, known as the Main Waterway. The structure regulates the water level of the largest river flowing through the city â the Oder. It includes hydraulic structures located in the area of the and â districts. Within this barrage are hydraulic structures such as the and the .
The barrage consists of two primary hydraulic components, i.e., water-regulating structures, as well as buildings and auxiliary or associated objects. The primary components of this barrage are:
In addition to the primary water-regulating structures, auxiliary and associated elements were built, such as bridges and footbridges for communication, technical and administrative buildings, residential buildings, and additional technical devices and structures.
The current form of the Bartoszowice Barrage is the result of an investment involving the construction of a new waterway and a new flood protection system for the city, as well as subsequent investments involving modernization and the construction of new objects. The original investment was carried out between 1913 and 1917. Some of the original structures within the barrage were reconstructed, while others were destroyed and dismantled.
In the post-war period in Poland, appropriate nomenclature was established for the structures and associated objects and canals. The names used for these objects derive from the district, located on the western, left bank of the Oder. For the lock and weir, names consistent with the Bartoszowice Barrage are used: Bartoszowice Lock and Bartoszowice Weir. Since the current structures were built when Wrocà Âaw was part of Germany, they also had earlier German names.
The Bartoszowice Barrage and the Opatowice Barrage, located on the City Waterway running through Wrocà Âaw, work closely together to regulate the Oder's water level up to the previous structure on the route, the Janowice barrage. For this reason, some authors of various publications treat the structures of both as a single entity, together with the local hydrological system, defining the Bartoszowice-Opatowice Water Junction.
The barrage includes water-regulating structures located in two canals, separated by a levee. The crown of this embankment is called Folwarczna Street. From the Bartoszowice district, Braci Gierymskich Street leads to the barrage, along which lies the Bartoszowice Bridge.
Wrocà Âaw is located on a canalized section of the Oder river. This means that the Bartoszowice Barrage is part of a series of structures maintaining the required water level on the river:
The waterway passing through the Bartoszowice Barrage is a waterway as defined by relevant legal regulations, specifically the Council of Ministers' regulation on inland waterways â a list of inland waterways, included in the list of inland waterways as an annex to this regulation. This is the , part of the international waterway EâÂÂ30. It is the main route for this waterway, with a secondary route passing through the Opatowice Barrage.
The Bartoszowice Barrage and the Opatowice Barrage are the first in the sequence of barrages in the . These two barrages, along with an additional sluice gate, control the entire water flow in the Oder through the city. The Opatowice Barrage directs water to the and the City Waterway, while the Bartoszowice Barrage directs water to the Main Waterway and the . The sluice gate allows the transfer of Oder waters to the Widawa via the .
The primary structures of the barrage are those that maintain the designated water level and perform other specific functions for which the structure is designed. The water level drop at the barrage for the normal water level is 3.7 m for the weir and 3.1 m for the lock.
Among the complementary and associated structures built within the barrage are:
Among the now non-existent structures is a steel bridge that once existed at the lock; it was destroyed during wartime operations and not rebuilt, with a footbridge constructed in its place in 2004.
