Darby Creek Valley Association has been conducting quality water monitoring throughout the Darby Creek Watershed since 2003 and Cobbs Creek, Darby Creek’s largest tributary, since 2014.
DCVA monitors 5 sites on the Darby Creek and 13 on Cobbs Creek for- (Darby Creek riparian habitat conditions, temperature and macroinvertebrates) - (Cobbs Creek - riparian habitat, macroinvertebrates, chloride, nitrogen, phosphorus, pH, conductivity, turbidity, salinity.)
In 2014 we joined the Delaware River Watershed Initiative (DRWI) and partnered with Stroud in 2017, to install, maintain and monitor an Enviro-DIY meter on an unnamed tributary to Cobbs Creek. The Enviro-DIY monitoring station measures conductivity, turbidity, temperature and water depth and those data (beginning on November 27, 2017) are uploaded auto-matically every five-minutes. See link below.
Derron LaBrake, one of our Board members, works extensive with Villanova and Temple Universities on a variety of stormwater related research, he even co-authored a research paper with Villanova in 2016. Mr. LaBrake also collaborated on a research project with the Academy of Natural Sciences at Drexel University in 2015 and 2016, that was assessing the potential impacts associated with a non-indigenous invasive plant that is taking over the riparian habitat throughout the region.
Our initial results are that both Creeks are impaired due to urban stormwater runoff. And unless, and until we get our urban stormwater runoff under control they will remain the creeks will remain the same, as a place that should be avoided when it rains.
