Town Lake Western Dam Replacement


The City of Tempe is replacing the inflatable rubber dam system at the west end of Tempe Town Lake with a new, hydraulically-operated steel gate dam.

The new dam is on schedule to be operational by Dec. 28, 2015 with work on the dam and associated projects beginning on June 4.

The new dam will be a reliable and cost-effective solution that is expected to last for decades. This page provides details about the project so that community members can follow its progress. Sign up for emails from us with updates at Scroll to the News section and click on Town Lake Updates.
