In particularly rainy years, the water level of the Amur River can rise as much as 45 feet (14 metres) above its usual level in the river's narrow upstream channels.1

While these monsoon-fed floods are significant, the impact varies by location. Downstream, where broad marshlands help capture excess water, the rise is much less pronounced, reaching only about 8 feet (2.5 metres) near the river's mouth. Additionally, it is important to note that ice jams in the river's sharp bends can cause temporary, catastrophic water level increases of up to 50 feet (15 metres).1
