Template: Infobox River / Obsolete
The Ik (Russian Ик, Bashkir Ыҡ, Tatar Ык, Iq ) is a 571 km long left tributary of the Kama in the Volga -Ural region of the European part of Russia. In Russian, the river is also called German Bolshoi Ik Ik Large, however, is not to be confused with the current flowing in the same region of the same name Bolshoi Ik, a tributary of the Sakmara in the river system of the Urals.
The Ik rises in about 320 m in the Bugulma - Belebeier heights, 13 kilometers northeast of the settlement Prijutowo and 16 kilometers south of the city Belebei. After a short course on the territory of the Republic of Bashkortostan in the south-west, the river turns abruptly to the north and is about 40 kilometers, the border of the Orenburg Oblast. While maintaining the predominantly northern flow direction of the Ik then traverses extending in the northwest -southeast direction of the main axis of the Bugulma - Belebeier ridge and marked on almost 150 kilometers in a straight line, the boundary between Bashkortostan and Tatarstan, leaving the river only for short distances.
Above the town Menselinsk turns to the river in west-north- westerly direction and then travels to its confluence with the Kama approximately parallel to within 10 to 15 kilometers away. The approximately 50-kilometer section of the parallel curve ( a straight line, the length of the actual river course is due to strong meandering greater ) is in the dam area of the Nischnekamsker reservoir whose level is normally 62 m. The common floodplain of Kama and Ik is a huge, up nearly 15 -kilometer-wide water surface - covered different outline - depending on water levels. The reservoir is here mostly less than two meters deep, as the raising of the water level was stopped on the originally planned level of 68 m in 1990.
The most significant tributaries are from the right and from the left Ussen Dymka, Mellja and Menselja, with the largest of which Menselja, today ends in the dam area of the Nischnekamsker reservoir.
The catchment area of Ik currently comprises 18,000 km ². Above the confluence with the Nischnekamsker dam the river reaches a width of 70 meters at a depth of about 2 meters.
The Ik freezes between the second half of November and mid-April. The average water supply in the village Nagaibakowo on the middle reaches of the annual average of 45.5 m³ / s
Economy and infrastructure
The Ik is navigable in the area of Nischnekamsker reservoir.
The -carrying area is mostly used for agriculture and is relatively densely populated. Largest city is Oktyabrsky, located directly on the right bank. The medium-sized cities Abdulino, Bawly and Tuimasy are only a few kilometers away from Ik to inflows. In the area of the upper and middle run, there are a number of oil fields, which are usually exploited since the 1950s.
In the upper reaches of the Ik between Abdulino Prijutowo and is crossed by the railway line Samara - Ufa - Chelyabinsk - Omsk, the south branch of the Trans -Siberian Railway. In Oktyabrsky the railway line Insa- Ulyanovsk- Tschischmy crosses the river, as well as the M5 highway Moscow - Samara Chelyabinsk. The M7 Moscow - Nizhny Novgorod -Kazan - Ufa crosses the river west of the village Poissejewo on her a few years ago completed the new route.
