Rainwater, Sediment and the Bay: Visual example of runoff

The last week several quick moving storms have dumped 1-3" of rain, and a bit of snow in the region we live in and that surrounds our beautiful Chesapeake Bay.{ } Here is a map from NOAA/NWS of the general rainfall this past week.{ }

{ }Some of the heavier rain (and some snow) fell { }to the north and east of the D.C. area but also over the{ }Susquehanna River drainage basin. For a time after one of the storms with moderate rain, more than 30 MILLION GALLONS of water was flowing down the Susquehanna.{ } Not only water but with generally bare soil in winter, also tons of soil.{ } The Susquehanna is the largest tributary to the Chesapeake Bay which is the largest estuary in the United States.{ } Here is a dramatic image Thursday from NASA's Aqua satellite (great images here){ }{ }

You can see the sediment (see the brown color in the Bay?) { }from that rain and runoff flowing into the northern{ } Bay, and flowing down the Potomac River.{ } Is this all due to human impacts?{ } Of course not, but it is an example of how we do have to be aware of land use and "best practices" to assure that "our Bay" stays as healthy as possible.
