LEQWhere is the land area that supplies runoff
to the Susquehanna River Watershed, and where
does all that water drain?

• Key Terms Headwaters Tributary Mouth

2
Headwaters

• The small streams near the source or beginning of
  a river system.
• Always in the highest elevations of the watershed
  and flow toward the lower elevations.
• Can flow in any compass direction.
• Join together to form larger streams.

3
Tributary

• The smaller streams and rivers that flow into a
  main river system.
• Always flow from higher elevations to lower
  elevations.
• Are part of a watershed.
• Can join together before they reach the main
  river system.
• The location where 2 streams or rivers come
  together is called a confluence.

4
Mouth

• The point where the main river system flows into
  a larger body of water.
• All of the water (and everything flowing along
  with the water) from the main river system flows
  into the larger body of water.
• The larger body of water can be a larger river, a
  lake, a bay, a sea, or the ocean.
• Always located at the lowest elevation of the
  watershed.

5
Watersheds

• Can be different in sizes.
• Can include only a few headwater streams,
  tributaries, and a small main stream.
• Small watersheds can be part of even a larger
  watershed.
• If part of a larger watershed, the smaller
  watershed is referred to as a sub-watershed or
  sub-basin.
• The mouth of the small watershed is a tributary
  or the main stream of the larger watershed.

Susquehanna River Watershed

• All of us in Central Pennsylvania live in the
  Susquehanna River Watershed.
• Like any watershed, the Susquehanna River
  Watershed has
• Headwaters
• Tributaries
• A mouth
• The Susquehanna River Watershed is a very large
  watershed that drains a very large area of land.
  Because it is so large, it has many
  sub-watersheds or sub-basins.

Susquehanna River Basin

• We will be using the internet to begin our map
  study of the Susquehanna River Basin.
• You will be given a worksheet to complete.
