The Agan ( Russian Аган ) is a 544 km long left tributary of the Tromjogan in the West Siberian lowlands in Russia .
course
The Agan flows from Lake Mensawemtor at a height of 78 m in the central part of the West Siberian lowlands, not far from the watershed between the right tributaries of the Ob and the catchment area of the Pur . It flows along its entire length in a westerly to south-westerly direction, always on the territory of the autonomous district of the Khanty and Mansi / Ugra , the swampy and lake-rich taiga landscape of the lowlands to its confluence at 32 m height in the Tromjogan, a good 60 km east-northeast of Surgut . Some sources regard the Agan as the right tributary of the Ob, and the Tromjogan as the right tributary of the Agan.
The most important tributaries of the Agan are Nankjogan and Amputa from the right and Wanjogan from the left.
Hydrography
The catchment area of the Agan covers 32,200 km². Near the mouth, the river is up to 200 m wide and 2.5 m deep; the flow velocity here is 0.5 m / s.
The agan freezes from late October to the second half of May. The water flow 87 km above the estuary is an annual average of 275 m³ / s with a minimum of 80.0 m³ / s in March and a maximum of 730 m³ / s in June.
Infrastructure and economy
The river is navigable for 360 km.
The development of almost the entire area through which the Agan flows began with the discovery of the West Siberian oil and natural gas deposits in the 1960s. The towns of Raduzhny and Pokatschi and the Novoagansk urban-type settlement , which are connected by roads to each other and to the Russian road network, were built on the river. Not far from the estuary and the eponymous village of Agan , the river is crossed by the railway line and the road that connect the cities of Surgut and Nizhnevartovsk on the Ob .
