The department's Dave Brent says the rented pumps are being installed in case the river depth drops below the 12 feet required for the city's largest pumps to operate.
"There's a design in a pump where it needs a certain water surface elevation over the top of it," says Brent. "If you get below that point, it can start cavitating which is basically drawing air in with the water and that can damage the pumps."
Brent says with Folsom Lake at historically-low levels the City will try to use as little American River water as possible.
But, the backup pumps will be ready to draw 24-million gallons-a-day if needed.
The Sacramento River pumping station is offline until March.
The city plans to have 13 million gallons per day of well water available once maintenance is complete on some city wells in the middle of February.
"The ground water in the area and in city itself is healthy," Brent says. "We've done, over the years, what we call conjunctive use, so in those wetter years, we try to utilize the river more and let the groundwater recharge. Now we're going to be more reliant on ground water."
Brent says well water could contribute 13 million gallons a day to the city supply. The Sacramento River station is expected to provide ten times that -the vast majority of the water needed this summer.
California's drought is blamed for a big downturn in honey production.
Researchers say California has been overdrawing its water account for a century.
Researchers at UC Davis fear that California’s drought may soon claim its first victim, the Red Hills Roach. The tiny fish is losing its water. Scientists fear it may soon be pushed to extinction.
A UC Davis report shows the drought has brought positive and negative effects to Lake Tahoe.
California's farm production costs totaled $36.6 billion in 2013, an 8.6 percent jump from the previous year. Higher rates for feed, labor, improvements and water contributed to the jump.
