From The Salt Lake Tribune (Brian Maffly):
The water rights behind the proposed Lake Powell pipeline are not actually coming from the project’s namesake lake, but rather from the major reservoir upstream on the Green River.
Now, Utah water officials’ new request to overhaul those rights has handed opponents a fresh opportunity to thwart the proposed pipeline just as federal officials are about to release a long-awaited environmental review of the $1.2 billion project, which would funnel 82,000 acre-feet of water from Lake Powell to St. George.
The request, known as a change application, seeks to shift the the water rights’ “point of diversion” from Flaming Gorge Reservoir to a spot 400 miles downstream behind Glen Canyon Dam. The change, which also keys into where and how the water would be used, is needed to fit the goals of the pipeline, which is to bolster water supplies for Utah’s mushrooming Washington County.
The application was filed now because the timing made sense at this stage in the project’s development and has no bearing on whether the pipeline gets built, according to Joel Williams, assistant director of the Utah Division of Water Resources.
Environmental groups hope to block or at least delay the project’s approval if they can persuade Utah State Engineer Teresa Wilhelmsen to deny the change application filed April 13. Exhibit A in the many protests filed is the Colorado River system’s chronically diminishing flows in the face of climate change, long-term drought and overallocation…
A 1922 interstate compact divvies up water flowing in the Colorado River and its many tributaries among seven basin states and Mexico. For decades, Utah has underutilized its share, pegged at 23% of the Upper Basin’s flows above 7.5 million acre-feet, while the three Lower Basin states have historically drawn water in excess of their allocations, largely to fuel urban growth and corporate agriculture.
