Colin Sonneveld and Steve Scott of NZOIA advise:
"There is a new log in the big rapid on the Upper Grey river section between Mc Vicars and the Staircase creek. The rapid is the longer one just after a right bend with the hole at the bottom. There are some logs sticking out of the big greywacke rock towards the top on river right. They are visible from above. The MAIN Log hazard is about two thirds down the rapid on centre left. The tree sticks out on a diagonal angle pointing river right. The level today was 2035 mm @ Waipuna gauge at 0630. At this level the log is exposed by 1.5 meters.
The grid reference is 260 L31 - 206721 Need to scout"
