 This is being done to fulfill obligations to downstream water rights holders. Visitors might notice heavy equipment accessing the lake from the north shore, placement of 40-foot sections of pipe for a temporary siphon and a drop in water during this time. 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.
