Jordan Lake Stakeholder Project 3 ..O~~O~ WAT~~pG y r >_ .., O ~ Jordan Lake Stakeholder Project Piedmont Triad Caancl! of Governments Reglonnl Geagraphtc fnformatfoa Systom 'T`riangle J F~ Ctluncil of Governments Purpose The Jordan Lake Stakeholder Project will result in a Nutrient Management Strategy for the Jordan Lake Watershed that will be presented as a recommendation to the Envirorrrrrental Management Commission- Background In the newly released draft .303(d) list, the New Hope River Arm of Jordan Lake is proposed to have a Total Maximum Daily Load (TMDL) developed to address elevated chlorophyll a levels resulting from excessive nutrient loads to the lake. Recently, nine local governments funded the completion of a nutrient response model for .Iordan Lake at a total project cost of more than $400,000. The model is a tool for predicting how different nutrient loads might affect lake water quality.. It will provide the technical basis for establishing the nutrient TMDL for all or pazt of .Jordan Lake. Based on the recently completed Jordan Lake Nutrient Response Modeling Project, it is estimated that nonpoint sources contribute about 70% of the total nutrient load to the New Hope Ann of the lake. Three major publicly owned wastewater treatment plants and several small privately owned "package" plants discharge highly treated effluent,just a short distance from the lake. Clearly, any future nutrient management strategy will need to address both nonpoint and point source loads, and include pazticipation from many diverse watershed stakeholders. Project Description The Jordan Lake Nutrient Response Model shows that increases in point and nonpoint source nutrient loads will further degrade lake water quality. If not managed properly, the population and economic growth that is projected to occur in the watershed over the coming decades will further tlueaten the ability of the lake to support its designated uses as a major regional drinking water supply, recreational resource, and aquatic habitat. The ".Jordan Lake Stakeholder Project" provides a fraznework for addressing these concerns, assisting the NC Division of Water Quality (DWQ) and the NC Environmental Management Commission (EMC) in developing the Jordan L,alce TMDL, and exploring the possibility of developing a Voluntary Nutrient Management Strategy for the Jordan Lake Watershed.
