The Ish (Russian Иж, Udmurt Оӵ, Tatar Иж / ij ) is a 259 km long right tributary of the Kama in the European part of Russia.

Course

The Isch rises in the center of the Udmurt Republic, between the villages Malije and Bolschije Oschworzy. From there it flows in a southerly and southwesterly direction, first by the densely wooded landscape.

After the confluence of the river Ljuk she turns to the southeast and shortly thereafter became the Ischewsker pond (Russian Ижевский пруд ) dammed. This 24 km ² artificial lake was built 1760-1763 for the water supply of the ironworks in the newly founded Izhevsk. Today, he serves the drinking and industrial water production.

After it has passed through Izhevsk, the Isch flows mainly in southern directions by a now increasingly utilized agricultural area. In this area they mändriert very strong and forms numerous oxbow lakes from. In Agrys they crossed the border with the Republic of Tatarstan. You now largely follows the boundary between Udmurtia and Tatarstan, this marked in parts even, but also changes several times between the two republics back and forth.

After the confluence of the Kyrykmas she turns to the southwest and you soon come to the pent-up for Nischnekamsker Kama Reservoir.

Hydrology and navigability

The Ish is navigable in its lower reaches during the ice-free period from early / mid- April to early / mid November. On the some -day breaking the maximum 50-70 cm thick ice follows the triggered by snowmelt spring floods, which supplies about 60 % of the annual runoff. At the outflow of the pond Ischewsker 200-250 m³ / s outflow are then measured.

Most summer annual Abflussminima be measured, moving around 1.5-2 m³ / s. The annual total runoff of Isch is 260-280 million cubic meters, between 140 and 180 million of them during the spring floods.

Below Izhevsk the river 22 to 28 m wide and 0.9-2.5 m deep. At low tide, the flow rate is an average of 0.12-0.15 m / s
