There are many springs and rivers in Florida. Freshwater springs, such as Blue, Wakulla,Alexander, and Deleon Springs. On the other side though rivers can be freshwater or brackish which is both salt and freshwater. There are few species endangered like the manatee. An interesting fact is the Nile river is the longest. What can you do while you're at a river or spring though? Go swimming!

Human Impacts

Positive Effects:

  • Dredge-Cleans out areas of water by getting rid of mud, or weeds.
  • Dam Construction-Dams are barriers to control flow of water and helps reduce amount of floods. Dams provide water and electricity to nearby cities.

Negative Effects:

  • Pollution-People can throw away their trash, poor drinks out, or leave items in rivers/springs which causes pollution and pollution can harm the animals or plants that live there.
  • Invasive Species-People can bring animals or plants that aren't native to Florida and it can affect other native species at Florida.
  • Saltwater Intrusion-Moves saline water into freshwater and can lead to contamination of drinking water sources. Freshwater springs can soon be filled with salt since of the saline water.
