This is today at Gavin's Mill fish ladder in central Milngavie. No rain for over a month and the main drop is dry enough to scramble all over taking pictures.
This was it a month ago with a day's rain and a fair amount of snow meltwater:
This is how it moves
What water is coming down today uses the fish ladder
A little further upstream, a rather nice footbridge and 500m upstream of that a pleasant looking waterslide. Nice sunny day.
