** ADVANCE FOR WEEKEND EDITIONS JUNE 6-7 ** In this May 31, 2009 photo, Lake Mead visitors enjoy a sunny day at Boulder Beach in Las Vegas. If Lake Mead's elevation falls another 23 feet, the water authority board will be asked to give the official go-ahead to construct the pipeline. The lake trigger is the newest addition to the authority's Water Resource Plan, which plots how the valley's wholesale water supplier expects to keep local taps running amid unprecedented drought on the Colorado.
