SRP emptying canals south of the Salt River

Posted: Updated:

PHOENIX (AP) -- Salt River Project canals south of the Salt River will empty starting Friday.

The Tempe-based utility says it will use the time to perform maintenance including the removal of silt and debris from portions of the South, Consolidated, Eastern, Tempe, Western and Highline canals.

SRP says crews will also comb canal banks and underwater structures looking for evidence of invasive adult quagga mussels

The mussels can clog pipes at power and water treatment plants.

They colonize rapidly on hard surfaces and can ruin boat motors.

The mussels were first discovered in 2008 at the head of the SRP canal system in the CAP-SRP Interconnect channel near Granite Reef Diversion Dam in east Mesa.
