17 Summer 2014 the Professional Engineer development controls. In addition, many of the point source discharges have moved ahead with eforts to reduce TN and TP in their discharges through operational changes. Tese actions have generally occurred in areas with the more moderate nutrient control require- ments. Te costs of extreme controls for new and existing development and some specifc requirements for point sources dischargers have resulted in the legisla- tive action for delay. Some legislation has called for an adaptive management approach – which is generally interpreted as "learn as you go" – but this approach also has both proponents and opponents. • While the in-lake treatment approach being demonstrated through the "SolarBees" is not likely a long-term solution to eutrophication problems, the demonstration and concurrent monitor- ing may provide some insight into the eutrophication issues in the lake and the likelihood of substantial change through nutrient reductions. Tis technology or other similar technologies may improve water quality conditions, but these technologies are not likely to resolve the base condition. Summary Jordan Lake has proven to be a valuable resource to North Carolina and the Triangle region. Te lake provides valuable food protection to downstream communities, is and will continue to be a valuable water supply for communities in and near the lake watershed, provides a much more stable and reliable source of water supply for down- stream communities than would be available without the lake and is an extremely valuable recreational resource to the region and state. While actions to protect this resource are very important, it also is important to recognize that the lake will remain a eutrophic piedmont reservoir. Focus on watershed based nutrient reduction strategies has the potential to help maintain the existing water quality conditions in the lake, and prevent future conditions from becoming a problem for meeting the uses of water supply and recreation.
