Twice a year, Byrne Creek Streamkeepers count bugs - the fancy name is "aquatic invertebrate surveys" - to assess the quality of the water in the urban stream. We sample the same locations year after year so that we have comparable data. The bug counts usually run for three weekends in a row.
The crew hard at work - we are fortunate to have members
who let us use their china and dining room tables so that we
can count in comfort after collecting the samples from the creek.
To our surprise, we found three baby crayfish in our sample.
Here's one of them next to a dime for size comparison.
