The Pregel, flowing through Kaliningrad Oblast and finding its way to Vistula Lagoon just outside of Kaliningrad, is a peculiar river. It starts where two other streams – Angerapp and Alle – join. At some point in time the current became so strong that the Pregel bifurcated into Pregel proper and Deime. Yet it was still not enough to keep the element at bay. Just outside of Kaliningrad, water flow gets so immense that the river meanders, creating islands and meadows so swampy that they have to remain largely uninhabited and serve only for summerhouses and fishing spots.
