Hydrology
The stream depth is over 155 metres at the mouth of the Shennong Stream, while 15 km upstream the depth diminishes to its original state uninfluenced by the Three Gorges Dam, i.e. approximately 30 cm in depth over riffles armoured with small rounded stones. Turbidity characteristics of the upper Shennong Stream are favourable with respect to most Chinese rivers, with Secchi disk measurements clear to at least 30 cm in depth;. The pH of the upper (natural) stream is in the range of .8.5. or slightly alkaline. (Lumina, 2007)
