The Havasu Divers Association is helping Central Arizona Project (CAP) fight the infestation of quagga mussels.

Beginning at noon Saturday, March 20, members of the Association will collect sample bags of live quagga mussels. Divers will be gathering at Site Six, a cove on the island. The site is marked by a red lighthouse on stilts.

The quaggas collected will be used to determine when the mussels die in the 336-mile-long CAP canal and attempt to determine why they die. CAP has determined that adult quaggas die in the canal but has been unable to determine what is killing the invasive species.

Water temperature in the canal is suspected to play a role in killing the quaggas so the live mussels collected by the divers will be placed along the CAP system before the water reaches its summer peak. The mussels will then be monitored.

 The members of the Divers Association think the mussels will be attached to discarded beer cans and they will collect the cans during the Saturday dive. Each year the Association removes thousands of beer cans from the lake.

CAP is the steward of central Arizona's Colorado River water entitlement and a collaborative leader in Arizona's water community. The 336-mile-long CAP system brings about 1.5 million acre-feet of renewable Colorado River water to its customers -- cities, businesses, agriculture and Indian communities -- in Pima, Pinal and Maricopa counties. An acre-foot of water is about 326,000 gallons.
