Rakhmanov Waterfall is a hydrological object of the Nature reserve Fund. The waterfall forms an unnamed stream located on the slope of the right side of the Rakhmanov Lake basin.
This stream originates from a small high-altitude (2265 m above sea level) moraine lake and flows into Rakhmanov Lake. The stream flows in a deeply cut hollow separating two unnamed mountains with absolute elevations of 2,400 and 2,280 m, respectively.
