Today we did an invertebrate study at our lowest monitoring site on Walley Creek. We haven't sampled for inverts since a Junior Streamkeepers Day with Dave Clough in 2017, but we read over Module 4 of the Streamkeepers manual and even checked out the Pacific Streamkeepers Federation YouTube page to get ready.
We sampled three times and found many mayfly and stonefly larvae, which are both intolerant to pollution. So, the presence of these fragile organisms in the creek means the water is clean and clear, with sufficient oxygen for aquatic life. It was exciting to find these important little insects!

I remember being transfixed by all the spawning salmon this creek in the fall when I walked to school as a kid. Just above Morningside Drive. But I don't recall seeing anything alive in there after that sewage treatment plant and subdivision were built.
