Runoff from agricultural land carries chemicals from fertilizers that collect in a lake. The buildup of chemicals can eventually cause--

• aquatic life, such as fish and turtles, to die from lack of oxygen

• excess water to fill the aquifer

• river tributaries to reroute, changing the flow of waterways

• rainfall levels to drop

When fertilizers enter surface water, they cause problems in 
the watershed by -

• increasing the amount of nutrients available to fish in lakes and streams.

• 
  clogging narrow streams and preventing water from flowing properly.

• raising the water level in nearby rivers to levels leading to flooding.

• causing rapid algal growth that decrease oxygen levels and choke aquatic life.
