Have you guys read any news stories about the costs of dealing with the quagga mussels in SD? I've searched online quite a bit and haven not been able to find any information as to the mitigation costs.

The San Diego Water District 2008 annual report makes a mention of what quagga mussels can do to water supplies, but doesn't say that they have done any of the items mentioned:

I think there is potentially a very interesting news story here. A story about how everyone cried that the sky was falling with quagga mussels and yet years later - has anything happened?
