Once a week, year round for 20 years, BES field researchers visited the 10 stream monitoring sites in the Gwynns Falls watershed shown on this modified Google Earth map. At each site they downloaded information about the week’s flow from monitoring equipment and take water samples for chemical analysis. The data, collected since the BES began in 1997, helps scientists understand the effects of land use on streams. These photographs were taken at or near the 10 stream sampling locations, between rural Oregon Ridge Park in Cockeysville, MD, and Carroll Park, in a heavily industrial section of southwest Baltimore City.
