The hydrograph above shows the arrival of the summer rainy season on June 19th, firstly with a series of minor rainfall events followed by a moderate flood peak on July 3rd, and a major flood event on July 6th. Total daily rainfall on July 6th was 85mm and 105mm at the local Miomote and Takane Amedas stations, where maximum intensities reached 29mm/h and 33mm/h respectively. These high intensities produce a flash-flood response, and river stage rose by as much as 30cm over 10 minutes.

Today I was joined by two doctoral students, Mirlan from Kyrgyzstan and Tsyden from Lake Baikal region in Russia. We measured discharge and confirmed no major changes in the rating curve, though there was some evidence of scour in the river bed. The water colour is light grey due to fine sediment being supplied at the upstream landslide site.

| Mirlan and Tsyden prepare to start the discharge measurement |
 |
| Flattened vegetation is clear evidence of how high the flood waters reached |
 |
| Cool water temperatures and warm humid air produce a river mist |
