There are three different projects that are at various stages in development or potential development.  What they share in common is that the proposed water transfers are significant in water quantity, distance the water will travel, the high cost of the pipeline, and that the water be transfered between basins.  The SNWA’s proposal is the costliest and is the only that involves transfering groundwater.  Water transfers in Utah and Arizona would take Colorado River and in the case of Utah would pipe water down a steep slope from Lake Powell to St. George.  The water would first be lifted up over Lake Powell and then down some 3,000 feet to St. George which could be used to generate electricity thereby alleviating some of the costs of the project.  The first step is for the federal government to file a right of way application that would precede federal environmental review of the project.   Perhaps most scary are predictions that by 2012 there could be water shortages in Southern Utah no doubt due to uncontrolled growth in St. George.  These communities need to get a handle on this growth and institute some if not all of the water conservation measures being used down the road in Vegas.  There is little difference in rates of precipatation between St. George and Vegas and so there is no reason that water should be wasted as it is now in St. George.  Generally speaking serious consideration needs to be given as to whether its feasible to support current development in this region as is based on current water demand.  The amount of time when experts are saying that these areas will face water shortages is very much in the near-term and there is no guarantee that these projects will fulfill demand even if they procede.
