Low water levels in Utah Lake is set to force state engineer Kent Jones to shut off the flow to secondary water users — a mandatory cutoff triggered when the lake reaches 125,000 acre-feet. This will leave nearly 41,000 residents of Riverton directly affected because the city has no other water source for lawns and gardens. The cutoff of lake water will leave the city’s secondary system without enough pressure to operate.

Excerpt From The Salt Lake Tribune:
Draper residents also use Utah Lake as the source for their outside watering, but Jones said Draper Irrigation Co. is believed to have alternate sources. The same is true with Kennecott, another Utah Lake secondary-water-rights holder. The lake already appears to be “significantly below the compromise level of 125,000 acre feet,” Jones said Friday as he was reviewing a draft letter to issue the cutoff order. “That officially marks a level where secondary storage rights have to be restricted and [users] can’t use that water anymore.”
