rover the Dog gets grouchy when he sees poo-lluted wa-

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!

Help Grover clean-up the City by “picking out” these words. Just find and circle the words:

Bugs that indicate Good Water Quality Bugs that indicate Poor Water Quality

A Mayflies—are sen-

sitive to most types of pollutants

A+ Stoneflies—are

sensitive to most types of

• pollutants. The presence
• f even a few stoneflies in

a stream suggests good quality water has been maintained for several months.

B Caddisflies—are

sensitive to pollutants, but some can be toler- ant

B- Beetles—require a

swift current and ade- quate supply of oxygen

F Midges—can have a

wide range of tolerances. The red ones (blood midg- es) are extremely tolerant to environmental stress, especially organic pollu- tion.

C- Crustaceans—can

thrive under conditions of high organic content and very low oxygen levels

D Snails—Some snails,

known as lunged snails, can thrive in poor water quality and during low flows be- cause they can breathe at- mospheric oxygen. Most snails are tolerant to a wide range of stressors.

D- Worms—can thrive

under conditions of severe pollution and very low

• xygen levels, thus are

valuable pollution indica- tors

Stonefly

Mostly found in cool, well‐oxygenated

• streams. They are sensive to most of

the same pollutants as mayflies except

• acidity. They may be less numerous

than mayflies. The presence of even a few stoneflies in a stream suggests that good water quality has been main‐ tained for several months

Perlodidae

Paerned Stonefly

These are some of the bugs that Grover knows best. Color in the bugs and learn what they can tell you about water quality.

Hydropsychidae

Common Net‐Spinner Caddis

Caddisflies

May construct a portable case of sand, stones, scks, or other debris or may spin nets that serve as a retreat and help them to collect and gather food. Many caddisfly larvae are sensive to polluon, but this family (Hydropsychidae) can be abundant in nutrient‐rich environments

Perlidae

Golden Stonefly

Mayflies

Mayfly nymphs are oen the most numer‐

• us organisms found in clean streams.

They are sensive to most types of pollu‐

• n, including low dissolved oxygen, chlo‐

rine, ammonia, metals, pescides, and

• acidity. Most mayflies are found clinging

to the undersides of rocks.
