Unfournately, I think its inevitable that most state water project lakes will end up infected.California has ones of the world's longest aqueducts that runs all over the state. If they get in there, I figure the pumps and gates won't be a real big deal for them to pass. If they can pass across the Great Lakes from interconnecting canals, our Aqueduct wouldn't appear to pose a block to their spread. But we should still take action. Quarantine needs to taken up for lakes not infected, but I figure its only a matter of time before the mussels will hit watersheds that recieve any type of water from state systems. For lakes that are infected, inspection systems should be placed at the exits, and washing systems at the ramps. Perhaps complete boat hoists, and wash stations, using very hot water or some type of chemical wash thats can kill mussel larva. Then you follow the washes with a hot drying machine, and inspect the boat before it leaves the lake gates.
