Poor water quality in lakes can have many unpleasant

consequences. Rough fish – such as carp and bullhead –

populations increase at the expense of game fish

populations. Severe nuisance algal blooms yield

unpleasant odor and appearance

that reduce the aesthetic appeal of

lakes. This may result in declines

in fishing and swimming and hurt

tourism.

As algae die and decompose, the

process consumes oxygen.

Submerged plants without sunlight

die, decompose and consume more

oxygen. Without enough dissolved

oxygen in the water, fish and other

organisms suffer and die because

they can't “breathe.” This can occur

locally or much farther downstream leading to degraded

estuaries, lakes and reservoirs. For example, fish and

other aquatic life can no longer survive in the so-called dead zone in the gulf of Mexico.
