A watershed is the area of land where all of the water that is under it or drains off of it goes into the same place. John Wesley Powell, scientist geographer, put it best when he said that a watershed is:
"that area of land, a bounded hydrologic system, within which all living things are inextricably linked by their common water course and where, as humans settled, simple logic demanded that they become part of a community."
Watersheds come in all shapes and sizes. They cross county, state, and national boundaries. No matter where you are, you're in a watershed!
Believe it or not, some of the water, especially in the rural and metro areas draw at least part of their drinking water from watersheds.
If you refer to Wikipedia they define a Drainage basin as follows.
A drainage basin is an extent of land where water from rain or snow melt drains downhill into a body of water, such as a river, lake, reservoir, estuary, wetland, sea or ocean. The drainage basin includes both the streams and rivers that convey the water as well as the land surfaces from which water drains into those channels, separated from adjacent basins by a drainage divide, water Shed or Water table .[1]
The drainage basin acts like a funnel - collecting all the water within the area covered by the basin and channeling it into a waterway. Each drainage basin is separated topographically from adjacent basins by a ridge, hill or mountain, which is known as a water divide. Other terms that can be used to describe the same concept are catchment, catchment area, catchment basin, drainage area, river basin and water basin.[2]
In the technical sense, a watershed refers to a divide that separates one drainage area from another drainage area.[3] However, in the United States and Canada, the term is often used to mean a drainage basin or catchment area itself. Watersheds drain into other watersheds in a hierarchical form, larger ones breaking into smaller ones or sub-watersheds with the topography determining where the water flows. Understanding geomorphology is essential in understanding how watersheds interconnect.[4]
Vickery Creek (Big Creek) is a creek located in Forsyth County and Fulton County in Georgia. The creek flows into the Chattahoochee River at the southern border of Roswell where State Route 9 crosses the river.
Much of the land east of the creek and west of Grimes Bridge Road in Roswell, Georgia, forms the Vickery Creek unit of the Chattahoochee River National Recreation Area.
Vickery Creek is named after a Cherokee woman named Sharlot Vickery that lived in present-day Roswell and owned much of the land around the creek. The creek was originally called Cedar Creek; however, the name was changed to Vickery some time after the arrival of Roswell King and family in 1834.[1]
The creek also became known as Big Creek at some point after the American Civil War.
1) Here’s what I’m looking for once you get to the cache sight. There is a type of hawk, heron, snake and at least two types of bats at this park, tell me what kind they are.
2) Storm water from East Park Creek is collected in a grassed area called an “infiltration forebay”. How many acres is it?
3) Once the water reaches the forebay, how many feet of rock does the water filter through?
4) How much of Roswell’s drinking water comes from the watershed and how much of it comes from the Chattahoochee?
5) Does a watershed offer soil erosion control?
E-mail me the answers but please do not post your answers in your log. Have fun and enjoy the walk. It should be a round trip walk of about 2 miles.
As always I need a picture of you at the coords or park itself in general.
Enjoy.
