Location of the Nara (Нара) in the catchment area of the Oka |
The Nara ( Russian Нара ) is a 158 km long left tributary of the Oka in the European part of Russia .
course
The Nara has its origin in Lake Polezkoye ( Russian Полецкое озеро ) in the southwest of the Moscow ridge , around 50 km west of Moscow in the west of Moscow Oblast . A few kilometers to the south it flows through the Nara Ponds ( Russian: Нарские пруды ), before continuing south through the densely populated Moscow area. A little later she reaches Naro-Fominsk .
About 15 km east of Balabanowo , the river crosses the border with Kaluga Oblast . It now flows further in a predominantly southerly direction to the northeast of the Kaluga Oblast, where it receives numerous smaller tributaries before turning east after the confluence of the Istja . The Nara reaches the border between the Kaluga oblasts and Moscow again. Here it turns again in a southerly direction, and now marks the border of the oblasts for a few kilometers.
Shortly afterwards it turns again to the east and now flows again in the area of Moscow Oblast. At Stankowo it turns south again, shortly afterwards it reaches Serpuchow , where it flows into the Oka.
Hydrology
The Nara has an average discharge rate of 5.5 m³ / s 80 km before its mouth . On average, it is frozen from late November / early December to April. The ice drift lasts about five days, the spring flood caused by the snowmelt on average 36 days from March to May, and provides around 46% of the annual runoff. Another maximum runoff is caused by rainfall between September and November. The river is not navigable due to its shallow depth.
