 The above picture was taken while water quality sampling under Rt50 bridge on the South River on May 29, 2009.  Notice the green-brown water color;  this happened to be a mixture of suspended sediment and an algae bloom.  The Secchi depth was only 0.2 meters or about 6 inches, meaning that sunlight could not penetrate below 1 foot.  The cause:  Stormwater runoff from the previous day's light rain bringing suspended sediment and nutrients from the headwaters (Bacon Ridge Branch and North River).   

I perform weekly water quality monitoring on the South River for dissolved oxygen, salinity, pH, conductivity, water clarity, turbidity and nutrients.  Since early May I have seen a drastic drop in water clarity and dissolved oxygen, this is very disturbing considering the hot weather is not here yet- what are we going to see this summer?
