Land Where the Water Flows

Attempt at outlining the Accotink Creek Watershed in Google Mymaps

The major neighborhoods that fall within the Accotink Creek Watershed are Fairfax City, Town of Vienna, and a grouping of suburban areas; Mantua, North and West Springfield, and Newington.  Also, part of the Army, Fort Belvior, resides in the watershed.

I tried to use googles mymaps to outline the topography of Accotink Creek watershed with reasonable success.  The inability to finely adjust the zoom feature inhibited more precision with outlining.  Some more research and playing around with the app may enlighten.  Fairfax county already has a very well established topography map database called 'Watershed Viewer' which allowed me to explore the different topographical options they had provided.

I plan on visiting one of the tributaries and photo-documenting the experience.  It will hopefully give a bit of life to the big-picture/birds-eye view that maps provide.  

Fairfax County's website provided the above Watershed Viewer screen captures along with information regarding the square footage but I wanted to try and calculate it myself using Microsoft paint, so below is just that.

Using the 2 mile legend I calculated mymap to 48sq2 miles of watershed area, where Fairfax has is designated at 51sq2 miles.  I was impressed with how close this rough calculation was to the one Fairfax has.
