days; fishing was not expected to resume until a year after the lake refilled. City officials indicated that they expected to reopen the lake by November 1, and that if the lake was reopened by then, the dam collapse's economic impact would be "fairly light." The city indicated that replacements for two of the remaining bladders had already been delivered and would be installed as soon as possible. The replacement for the failed section was delivered to Tempe by the middle of August. The city built a cofferdam to allow the lake to be refilled while the northernmost bladder was replaced at a later date. Some of the fish that had temporarily survived the dam break and were left stranded in shallow pools of water in the lake bed were scooped out and fed to a captive alligator in the parking lot of the Tempe Center for the Arts on Friday, July 23. Most of the fish removed from the lake were to be fed to other denizens of the Phoenix Herpetological Society, where the alligator has lived since 2005. On October 8, 2010, SRP crews began refilling the lake. Water used to refill the lake was brought down the Salt River reservoir system from Roosevelt Lake east of the Phoenix area. Tempe officials chose to use a portion of their allotment of Lake water since the Lake was filled to capacity at the time. This method saved the city hundreds of thousands of dollars versus the alternative of filling it with Colorado River water from the CAP. After about two and a half weeks, the lake was reopened for normal water activities on October 26, 2010. Notable water releases The Salt River bed in the Phoenix metropolitan area is often either dry or flowing to a trickle, with the river's water being entirely diverted to agricultural and other uses upriver. Since Tempe Town Lake uses artificial structures and the natural riverbed to form the lake, the inflatable dams confining the lake must be lowered in periods of high runoff to permit the passage of the Salt River itself. The lake has released water on multiple occasions as the river levels rise normally due to heavy rain or winter snow runoff. On December 31, 2004, the eastern dam was lowered for the first time since its construction. Heavy rains in the Salt River watershed required the release of of water
