East Siberian Sea runoff into the East Siberian Sea is relatively small at about 250 km/year that makes only 10% of the total runoff in all the Arctic seas of Russia. The largest contribution is from the Kolyma River at 132 km, followed by the Indigirka River at 59 km. Most runoff (90%) occurs in summer; it is concentrated near the coast, owing to the weak river currents, and therefore does not significantly affect the sea hydrology. The water exchange between the neighboring seas is as follows. The annual outflow to the Laptev Sea, Chukchi Sea and Arctic Ocean is 3,240, 6,600 and
East Siberian Railway In 1887, three expeditions were organised to explore the route for the future Trans-Siberian Railway. In May 1893, the Committee for the Construction of the Siberian Railway was created. The construction of the Trans-Siberian Railway was launched simultaneously from its two extremities, namely Vladivostok and Chelyabinsk. By 1895, the construction of the section of railway from Chelyabinsk to the railway station of Ob near the small settlement of Novonikolaevsky (today's Novosibirsk) was complete. On December 6, 1895 the first train arrived at Krasnoyarsk, which would become a starting point for the construction of the East Siberian Railway towards Irkutsk and
