Byrne Creek Summer Bug Count
The Byrne Creek Streamkeepers completed their summer aquatic invertebrate survey today -- or bug count -- and the results were satisfactory. All of the samples were in the 2.0 - 2.5 range for water quality on a scale with 4 being good. Not bad for an urban creek that faces a constant flow of pollutants from storm drains. Thanks to leader John for organizing the three weekend counts and Dave for tallying the results. Here's one of Dave's charts:
We use the standard Streamkeeper's Handbook method of surveying. The types of bugs and their numbers indicate the quality of the water.
