Symposium Agenda


The UNC Institute for the Environment collaborated with the Upper Neuse River Basin Association (UNRBA)  to provide the 2022 Falls Lake Nutrient Management Strategy and Research Symposium.

The symposium featured updates from researchers from UNC, NC State, and East Carolina University, as well as the UNRBA.
