Tempe Town Lake Scheduled to Close for More than a Month Next Spring

Replacing the current inflated rubber Tempe Town Lake dam with concrete and steel will shut down the lake—probably next spring—for a period the city estimates will be more than one month, severely affecting activities for Arizona Yacht Club and the Arizona Sailing Foundation.

Tempe Senior Boating Coordinator Alicia Jerger announced the plan in an email, saying the new concrete and steel dam will be finished in “February or March,” depending on weather delays. At that point the city will divert the TTL water and, she says, “It is anticipated that refilling of Town Lake, mostly using water exchange credits, will begin one month after the water is diverted. Tempe Town Lake will be closed to boating and water recreation once the water diverting has begun.”

The new steel gate dam system  includes 8 gates that will be hydraulically controlled to open for flood control. Here’s a link to the Tempe web page that includes videos describing the new system.

Obviously closing the lake will throw the AYC and ASF schedules into chaos, especially since it’s not possible to plan much in advance for the closure.
