Longitudinal sampling on Wissahickon

flowmeterWe spent a day getting samples from the headwaters to the Philly border along the Wissahickon and its tributaries.  Sarah, Marley and I each took a section of the creek to sample the day.  For this round of sampling, the flow was low and we are doing a careful analysis of different forms of phosphorous.  Sample analysis is underway!  We got low flow discharge along the creek the following week.
