Leonard Willett, the Bureau of Reclamation's quagga mussel coordinator for the lower Colorado River dams, said the effort to deal with quaggas, which were discovered last year first in Lake Mead and later downstream of Hoover Dam, still is in the monitoring phase, the first part of what he called the "reactive approach.
"Reactive approach means you're going to live with the mussels.
You're going to control them, but you're going to live with them," he
said in a recent presentation to the Lake Mead Water Quality Forum
projected that as the infestation sets in and begins to clog hydroelectric power cooling pipes and other hardware in Hoover Dam's
operations, the maintenance-and-control bill could reach $1 million a year, especially if pipes get plugged with quagga colonies.
That could cause turbines to overheat and shut down until cooling pipes can be reamed of the invasive species.
"This is an evil critter, not good," Willett
