| Takiya stage hydrograph showing flood of 28-29 July |
The record-breaking rains that hit central Niigata Prefecture over 28-30 July were not so intense in northern Niigata and the Miomote Basin. In the stage hydrograph above we can see a double peak flood over 28-29 July and the maximum stage of about 1.3m is only a medium size flood for the Takiya Basin.
Today I visited the field to check the situation after the rains and to make a routine discharge measurement. I had to clean some debris from around the staff gauge, and there were some new deposits of gravel on both the left and right banks. Horsefly ("abu") season is in full swing, but I was not troubled so much by them. If you keep still, then they seem to disperse. No leeches today - the ground is baked dry after hot dry weather all this month.
