Which would indicate the water in a lake is not safe for drinking?

• Many varieties of fish in the lake

• high dissolved - oxygen levels in the lake

• The temperature of the lake water will decrease.

• The turbidity levels of the lake will decrease.

• The dissolved- Oxygen levels in the lake will increase.

• The growth of algae in the lake will increase.
