Th e transboundary Russian-Chinese Lake Khanka is characterized by a complex and poorly predictable hydrological regime with long-term cyclic fl uctuations of the level. Th e last rise of the level, which began after 2000 year, turned out to be anomalous in the entire history of observations and caused severe fl ooding of the coastal territories of the Russian part of the basin with related intensifi cation of erosion processes, impact on ecosystems, etc. Th e main factors aff ecting the hydrological regime of the lake are climatic changes in the region and anthropogenic impact on the water resources observed in the Khanka Lake catchment area because of the development of irrigated agriculture, especially in the Chinese part of the basin. Th e reduction in the capacity of the Sungacha River due to the deposition of sediment in the source of the riverbed make current state of the lake’s water regime worse.
