"I suggest you be on the ready," he added, "come late August or September."
Because of its storage capacity in Strawberry, Starvation and Jordanelle reservoirs, the Central Utah Project should be able to fulfill all of its contractual obligations to supply water to customers, Jensen said.
But the two biggest districts that supply water to Salt Lake Valley residents the Jordan Valley Water Conservancy District and the Metropolitan Water District of Salt Lake City and Sandy will face greater supply problems because more of their water comes from the mountain snowpack above Salt Lake.
"Unless we get some more moisture, you could see the possibility of rationing at some level," Jensen said.
As of Tuesday, the water content of the snowpack in the "Cottonwood Canyons Group" of measuring stations was 59 percent of normal, according to the Colorado Basin River Forecast Center.
About 9.2 inches of water is in that snowpack now; 15.5 inches is the median amount over the past 30 years, the Forecast Center's website said.
Jensen, whose third public role is as chief of the Unified Fire Authority, then cited the drought's impact on the threat of wildfires. Blazes already have begun in southern California, sweltering through one of its worst droughts in a century. Ski resorts around Lake Tahoe are desperate for snow.
"The whole Sierra Basin is in a critically extreme position. It's not good for the whole West," he said. "It's a big issue if we don't get some moisture."
Air quality concerns
The Salt Lake County Council unanimously endorsed Councilman Arlyn Bradshaw's effort to secure a seat on the Utah Board of Air Quality.
Because air quality is such a concern to residents of the state's most populated county, Bradshaw said the county should have a voice on the state board responsible for pollution control.
He is seeking to fill an opening created when county government's representative on the board, Cache County Councilman Craig Petersen, became mayor of Logan. Gov. Gary Herbert will appoint Petersen's replacement.
"I represent a constituency that is very active on air-quality issues," said Bradshaw, a Democrat from Salt Lake City, suggesting the state could be more flexible in allowing counties to deal with their own pollution problems.
"It's important for somebody from Salt Lake County to be on the board," he added, adding that the unanimous vote by the Republican-majority board "showed that they agree."
