The 380 km long Jaja ( Russian Яя ) is a left tributary of the Chulym in Siberia ( Russia , Asia ).
The Jaja rises near the settlement Jaschkino in the northwest of the Kemerovo Oblast , flows first in an easterly direction , then after taking up its right tributary Barsas partly strongly meandering through the southeastern part of the West Siberian lowlands in a northerly direction. At the settlement of Jaja , the river is crossed by the Trans-Siberian Railway and finally flows into the Tschulym ( 95 m ) about 10 km above the city of Assino ( Tomsk Oblast ).
The catchment area covers 11,700 km². The mean monthly water flow in the village of Semjonowka, 22 km above the mouth, is 82.7 m³ / s (minimum in March: 11.5 m³ / s, maximum in May: 500 m³ / s). The river there is 108 m wide and 0.7 m deep; the flow velocity is 0.4 m / s.
The Jaja freezes from late November to April.
It is navigable for 114 km from the estuary (to the village of Novostroika below the confluence of the left tributary Kitat ), but is not used regularly for inland navigation.
