Tempe Town Lake is full again after only 12 days of releasing water into it.
The Salt River Project shut off the flow of water at 10 p.m. Tuesday once the lake rose to its ideal level, SRP water engineer Tom Sands said Wednesday.
SRP expected the refilling could range from 12 to 20 days, based on how much water could safely flow through a channel in Papago Park. The water began flowing into the lake at 50 cubic feet per second on Oct. 8, but by the next day had been increased to 100 cfs. That’s about enough water to fill a swimming pool in 30 seconds.
SRP will tinker with the lake level by the time Tempe officially reopens the 998 million gallon lake Tuesday. The lake may have another inch or two of water by then as Tempe and SRP officials monitor new rubber bladders on the lake’s west end to determine how much more water can fit in the lake.
“At the city’s direction, we’ll be putting in a little bit more water,” Sands said.
The new dams are about a foot lower than the bladder that burst on July 20 and emptied the lake.
SRP will now resume its daily monitoring of the lake level to determine whether it needs to add water. The lake hasn’t needed any water from SRP in the last two or three years, Sands said, because of a slight flow in the Salt River that has trickled into the lake at least as fast as water has evaporated.
Tempe will formally reopen the lake during a 6 a.m. Tuesday ceremony at the marina.
