Spatterdock is a common freshwater plant of Florida. Its heart-shaped, large leaves may be wide or narrow and are often floating. Spatterdock flowers are yellow and grow at or above the water surface. S-12 D was built by the U.S. Army Corps of Engineers. It is a spillway that passes water, via canals, from WCA-3 to Everglades National Park.
Gates can either hold water in or let water out.
Pumps are used to pump water from one location to another.
