G rover the Dog gets grouchy when he sees poo-lluted wa- ters. He is on a mission to teach us about im- proving our water quality . A message from Grover: The quality of this water is gross So, let’s do something about it! You can see in the picture to the right how water from rain can get dirty on its way to the river. We play in these waters, and drink it also. Learn how you can help!

You can learn a lot about water quality from a bug. Bugs that indicate Bugs that indicate Good Water Quality Poor Water Quality C- Crustaceans—can A+ Stoneflies—are thrive under conditions of sensitive to most types of pollutants. The presence high organic content and very low oxygen levels of even a few stoneflies in a stream suggests good quality water has been maintained for several months. D Snails—Some snails, known as lunged snails, can thrive in poor water quality and during low flows be- cause they can breathe at- A Mayflies—are sen- mospheric oxygen. Most sitive to most types of snails are tolerant to a wide pollutants range of stressors. D- Worms—can thrive under conditions of severe B Caddisflies—are pollution and very low oxygen levels, thus are sensitive to pollutants, valuable pollution indica- but some can be toler- tors ant F Midges—can have a wide range of tolerances.

These are some of the bugs that Grover knows best. Color in the bugs and learn what they can tell you about water quality. Perlodidae Pa � erned Stone fl y Stone fl y Mostly found in cool, well ‐ oxygenated streams. They are sensi � ve to most of the same pollutants as may fl ies except acidity. They may be less numerous than may fl ies. The presence of even a few stone fl ies in a stream suggests that good water quality has been main ‐ tained for several months source: Nymphs of North American Stonefly Genera; by Kenneth W. Stewart & Bill P. Stark
Hydropsychidae Perlidae Common Net ‐ Spinner Caddis Golden Stone fl y Stone fl y Caddis fl ies Mostly found in cool, well ‐ oxygenated May construct a portable case of sand, streams. They are sensi � ve to most of stones, s � cks, or other debris or may spin the same pollutants as may fl ies except nets that serve as a retreat and help them acidity. They may be less numerous to collect and gather food. Many caddis fl y than may fl ies. The presence of even a larvae are sensi � ve to pollu � on, but this few stone fl ies in a stream suggests that family (Hydropsychidae) can be abundant good water quality has in nutrient ‐ rich environments been maintained for source: Nymphs of North American Stonefly Genera; by Kenneth W.

Heptageniidae Flat Head May fl y May fl ies May fl y nymphs are o � en the most numer ‐ ous organisms found in clean streams. They are sensi � ve to most types of pollu ‐ � on, including low dissolved oxygen, chlo ‐ rine, ammonia, metals, pes � cides, and acidity. Most may fl ies are found clinging to the undersides of rocks. source: Aquatic Entomology; by Arwin Provonsha
