How does fertilizer runoff harm fish?

Fertilizer that washes into a creek feeds algae, which can grow into a thick bloom. When the algae die, bacteria break them down and use up much of the oxygen in the water, so fish cannot get enough.

What are buffer strips?

Buffer strips are wide bands of grass and shrubs between fields and a creek. The roots soak up water and fertilizer before runoff reaches the creek.
