Jordan Lake was declared as nutrient-sensitive waters (NSW) by the North Carolina Environmental Management Commission from 1983, the year it was impounded. The lake is eutrophic or hyper-eutrophic owing to excessive nutrient levels.
The North Carolina Environmental Management Commission (EMC) has adopted Nutrient Roles for Jordan Lake and Falls Lake and NCDOT's GREEN Program guides the Department's compliance. These rules establish nutrient management strategies designed to reduce algal growth in the lakes.
NSW Strategies - Neuse River Basin Nutrient Sensitive Water Management Strategy: Agricultural Nutrient Reduction Strategy Environmental conditions in the Neuse River are driven by complex interactions among rainfall, flows, temperatures, biological factors, and chemistry. Water because of the long-term eutrofication of its estuary. In 1996, the North Carolina General Assembly passed House Bill 1339, which set a goal of reducing nitrogen loads to the estuary by 30 percent by 2003 (with 1995 as the baseline year). In 1997, the Neuse River Nutrient Sensitive Waters Management Strategy was developed
