The Vistula is the most important river in Poland, which runs from the high hills in the southern region to the northern Baltic Sea. The significance of the Vistula is river length, high flow, and broad tributaries. The average yearly flow of the Vistula to the Bay of Gdansk is much more than 1000cubic m / sec. River length equals 1047 kilometers from its origin to the point of discharge.
Sometimes, it is characterized into two sections The Small Vistula from the source to the tributary (about 106 km) – Przemsza River. The rest is around 941km long, classified as Navigable Vistula. The complete flow of the Vistula is on the territory of Poland.
Within the last million years, an ice sheet crossed the region of Poland 8 times, bringing along with its modifications of course of the river. When the ice sheet receded in warmer eras, the Vistula deepened and extended its valley. The river took its current form within the last fourteen thousand years, after the complete retreat of the Scandinavian ice cap from the area. Now, including the Vistula valley, degradation of the banks and gathering of new deposits are still occurring.
Further, The Vistula is also in the middle of Europe. The country’s three primary geological and geographical landmasses meet in its river system: the lowland Eastern Europe a shield and the Alpine zone of mountainous areas to which the Carpathians and Alps belong. The Vistula starts in the Carpathian highlands. The flow and nature of the river were created by ice sheets coming down from the Scandinavian peninsula. The ice sheet entered the territory of Poland roughly 20,000 years ago. During seasons of warm temperatures, the old Vistula, “Pra-Wisła”, looked for the quickest course to the sea—thousands of centuries back, it flowed into the North Sea, in the latitude of modern Scotland. The weather of the Vistula valley, its wildlife, plants, and nature altered drastically during the glacial retreat.
The Vistula can be split into three parts: upper, from its headwaters to Sandomierz; center. Second, from the Sandomierz to the convergences with the Narew and Bug. Third, from the junction with the Narew to the sea.
The Vistula river basin comprises 194,424 sq. km. Its average altitude is 270 m (about 886 feet) above sea level. In addition, most of its river basin is 100 to 200 m over sea level; about 3⁄4 of the river basin spans from 100 to 300m in altitude. The maximum height of the river basin is 2,655m. One of the hallmarks of the river Vistula is its inequity, arising from the tilt motion of the European Lowland to the NW, the direction of the passage of glacial waters, and the strong propensity of its older base. The asymmetries of the river basin are around 73–27 percent.The most recent glacial of the Pleistocene epoch, which ended around 10,000 BC, is dubbed the Weichselian glaciation or Vistulian glaciation in north-central Europe.
The fishery is around 30 kilometers long. Thus, there are plenty of exciting spots along its banks. Plus, shoots are common in the Vistula. Moreover, the best period for journeys to the river is the end of winter or spring. With higher waters, it is simpler to fool the brown trout in this period. Indeed, the Vistula is one of the rivers above the national average as far as its fish population is concerned. Well, if you wish to fly fishing and try brown trout, the Vistula river is the best place in Poland.
