Pregolya
The Pregolya or Pregola (; ; ; ) is a river in the Russian Kaliningrad Oblast exclave. Name A possible ancient name by Ptolemy of the Pregolya River is Chronos (from Germanic *''hrauna'', "stony"), although other theories identify Chronos as a much larger river, the Nemunas. The oldest recorded names of the river are ''Prigora'' (1302), ''Pregor'' (1359), ''Pregoll, Pregel'' (1331), ''Pregill'' (1460). Georg Gerullis connected the name with Lithuanian ''prãgaras'', ''pragorė̃'' ("abyss") and the Lithuanian verb ''gérti'' ("drink"). Vytautas Mažiulis instead derived it from ''spragė́ti'' or ''sprógti'' ("burst") and the suffix -''ara'' ("river"). Overview It starts as a confluence of the Instruch and the Angrapa and drains into the Baltic Sea through the Vistula Lagoon. Its length under the name of Pregolya is 123 km, 292 km including the Angrapa. The basin has an area of 15,500 km2. The average flow is 90 m3/s. Euler's Seven Bridges of Königsberg pro ...

Angrapa
The Angrapa (, , , ) is a river that begins in northeastern Poland and ends in the Kaliningrad Oblast of Russia. Originating in Lake Mamry, it joins the 101-km-long Instruch at a point near Chernyakhovsk – variously assessed as lying 140, 169, or 172 km from its source – to form the Pregolya. Its largest tributaries are the 89-km-long Gołdapa, which joins just before the border, and the Pissa (98 km). The name Angrapa is derived from the Old Prussian words ''anguris'' (eel) and ''apis'' (river). The towns of Węgorzewo, Ozyorsk and Chernyakhovsk as well as the village of Mayakovskoye, are situated along the course of the Angrapa.

River
A river is a natural stream of fresh water that flows on land or inside Subterranean river, caves towards another body of water at a lower elevation, such as an ocean, lake, or another river. A river may run dry before reaching the end of its course if it runs out of water, or only flow during certain seasons. Rivers are regulated by the water cycle, the processes by which water moves around the Earth. Water first enters rivers through precipitation, whether from rainfall, the Runoff (hydrology), runoff of water down a slope, the melting of glaciers or snow, or seepage from aquifers beneath the surface of the Earth. Rivers flow in channeled watercourses and merge in confluences to form drainage basins, or catchments, areas where surface water eventually flows to a common outlet. Rivers have a great effect on the landscape around them. They may regularly overflow their Bank (geography), banks and flood the surrounding area, spreading nutrients to the surrounding area.
