Malone, S.J., R.G. Lathrop, E. Pyshnik, J. Blum, J. Whytlaw, and J. Bognar. 2019. State of the Raritan Report, Volume 2. Sustainable Raritan River Initiative, Rutgers, The State University of New Jersey, New Brunswick, NJ. Rutgers University’s Sustainable Raritan River Initiative has released a second report on the status of watershed health for the Raritan River. The State of the Raritan Report, Volume 2 continues efforts to update key indicators of water quality and watershed health for the Raritan River basin. The health of the Raritan basin was originally assessed in the 2002 Raritan Basin: Portrait of a Watershed as developed by the New Jersey Water Supply Authority and updated in the Sustainable Raritan River Initiative’s 2016 State of the Raritan Report, Volume 1. The objective of those reports, and this one, is to inform watershed management planning and water supply protection needs in the Raritan basin.
