The river levels are the lowest I've seen in 52 years and now the water is covered in duckweed.    The fish are constantly jumping out of the water, for a gasp of oxygen I guess, which in turn makes Luna jump too.   I'm hoping she doesn't fall in as the level has dropped by about 600cms, it would be difficult to reach down to haul her out, and as the sides are straight down she wouldn't be able to clamber out on her own.
