Water Quality Indicators

Water with high turbidity 

• is cloudy and hard to see through
• is clear

Macroinvertebrates such as stoneflies, mayflies and water boatmen require high levels of dissolved oxygen and their abundance is an indication of:

• Poor water quality
• Good water quality
• Don't tell us anything about water quality
• Invertibrates don't tell us anything about water quality
