Foam in Byrne Creek
There was a suds event in Byrne Creek this afternoon. When I started on my walk shortly after 11:00 the creek was clear. I spent some time sweeping the lower reaches, the spawning channel, the sediment pond, and the overflow pond for fry, but saw nothing -- no fry, no smolts, no cuts, zip.
On my way home I took the upper ridge trail, and about halfway along I spotted a pileated woodpecker, and as I was lining him up in my camera, I noticed the creek way down below was quite foamy. Snapping a few shots of the woodpecker, I headed up the hill and found almost no sign of foam in Griffith's Pond near the skytrain station. When I went down the Ron McLean path, there was quite a bit of foam coming down from upstream of the Hell Hole at around 1:15. So the source was likely somewhere upstream of Griffiths.
