2019 Jordan Lake Nutrient Management Study Research Symposium

Wednesday, April 3, 2019

10:00am – 3:00pm
North Carolina Botanical Garden
Chapel Hill, NC

The purpose of this symposium was to share the breadth of research happening as part of the Jordan lake Nutrient Management Study and facilitate dialogue among various stakeholders within the Jordan Lake watershed.

More than 100 stakeholders from throughout the Jordan Lake watershed gathered to hear from researchers from UNC-Chapel Hill and NC State. Topics included in-lake factors affecting algal growth, watershed inputs affecting algal growth, integrating scientific findings into modeling efforts, and funding nutrient management efforts.
