The bottom of the Urmi valley has altitude about a kilometer
In the upper reaches Urmi is swift and shallow
The only fish I was able to catch is yellowspotted grayling; it is considered a relative to the Upper-Amur grayling. In the Lower Amur this species is living together with the Lower-Amur grayling. Yellowspotted grayling is occupying areas close to the source of the rivers.
My lab at the river bank
The river has big gradient - over 1:100; the current during floods is very strong. You could see it by the size of the boulders at the banks.
A small tributary
After a strong rain a small river with 15:1000 gradient becomes a torrent
Unusual red lichens
This form of grayling is easy to distinguish from other grayling species by a yellow spot at the dorsal fin
