Creek Critters App

Ready to start monitoring, but not quite ready to take on official training and certification? Creek Critters has got you covered! This app guides you step by step through the process of finding and identifying bugs in your stream.

Perfect for families, public programs, and even as a solo activity, Creek Critters is easy and fun. Collect bugs by following simple step-by-step instructions, and identify your bugs with an interactive identification key.

Once you’ve identified your bugs, Creek Critters does the rest! The app automatically calculates your Stream Health Score based on your findings. The score tells you how healthy your stream is – plus your results are added to the Clean Water Hub, our public database of water quality in America.

Download Creek Critters FREE from the Apple Store or Google Play Store.
