Watersheds made simple

  1. 1. A simple definition A watershed encompasses all of the land area that drains to a given water body. When it rains, all of the land within a watershed, drains by gravity descending downwards across the land into creeks, streams and smaller tributaries and on to larger rivers and eventually to its receiving water body such as an enclosed lake, ocean or gulf.
  2. 2. Components of a watershed1. Divides are found at the top of the system and separate one watershed from another.2. Watersheds are usually named for their receiving water body.3. Tributaries are smaller streams or creeks that feed or flow into a larger stream or river. Large rivers have many tributaries that flow into them. These tributaries each have their own smaller watersheds.4. The headwaters are found at the top of a river system and are where the river, stream or creek begins.
  3. 3. This map is of anarea in Florida thathas 10 majorwatersheds.Each of these 10major watersheds ismade up of manysmaller microsheds.This map can be found at sjrwmd.com
  4. 4.  We all live within a watershed. We all live downstream. We all live upstream. All of us that live upstream contribute, for good or for ill, to the quality of life for all who live downstream.
  5. 5.  Smaller waterways feed into larger waterways.Arrows showthe directionof water flow.
