According to the State Water Registry [2] and modern topographic maps [3] , it is the left tributary of the Istra , and the Nakhabinka is the left tributary of the Gryazev [4] .

Hydrology
If we assume that the Gryazev is an Istra tributary, then its length is 26 km, and the basin area is 109 km² [2] . If we assume that the Gryazev is a tributary of the Nakhabinka, then its length is 11 km [7] .
Historical inaccuracy
On pre-revolutionary maps, the Nakhabinka River is designated as a tributary of the Istra, and the Gryazev River is the left tributary of the Nakhabinka [8] . On Soviet topographic maps, the Nakhabinka is marked as the left tributary of the Gryazev, which flows into Istra. Thus, in the 20th century, the rivers Nakhabinka and Gryazeva changed places on the maps. Modern place names are inaccurate from a historical point, since, according to topographic maps, the Nakhabinka River does not flow through the urban-type settlement of Nakhabino [5] .
