 According to officials, the siphon opening will be 60 feet underwater and screened. Installation is expected to be complete this Friday, and the total project is expected to take two weeks to complete. Visitors are asked to stay clear of the pipe, particularly during installation and removal. Work near the spillway is scheduled between 6 a.m. and 3 p.m. daily, during which time there will be fewer parking spots and visitors will not be able to hike the full loop around the lake off Walker Road. This is Russ Edwards reporting.
