Zebra Mussels Found in Redgranite

[jrkmbeck]

Last week when I was on a dive charter the subject of Zebra mussels came up.  One of the guys we were diving with said that someone had placed some Zebra mussels in a quarry that he dived in many times.  The water became clearer for a short tiem but then the mussels all died and the algee and wahtever that resulted from the massive die off made the quarry almost impossible to dive.  It stank and the vis went to under two feet.  Don't know how factual this is, but if this is all true it could spell trouble for an otherwise good quarry.
