Rogue Boat Incident
In the middle of March, officials in California sent a message to states north warning abouta pontoon boat from Montana that was potentially packing an insidious cargo.
The boat had spent some time in Lake Havasu, where invasive quagga mussels are known to lurk.

This subspecies is indigenous to the Dnieper River drainage of Ukraine.
National Park Service:
Now there is a new and serious threat.
Imagine a future where going to your favorite rock-skipping beach, you find the shoreline matted with tens of thousands of small mussel shells, with everything cemented together in a sharp, smelly mess.
Imagine once productive fisheries wiped out by these new invaders.
It's not science fiction, impacts are already occurring in waters in the Great Lakes, eastern provinces and states, the prairies and plains, and more recently in the southwest United States.

I wonder if they are edible?
Could make massive vats of "clam" chowder...
Although quaggas are edible for humans, eating them is not recommended due to the accumulation of toxins, pollutants, and microorganisms within the mussels' bodies.[
The zebra mussel (Dreissena polymorpha) is a small freshwater mussel. This species was originally native to the lakes of southern Russia, being first described in 1769 by the German zoologist Peter Simon Pallas in the Ural, Volga and Dnieper rivers. These mussels are still found nearby, as Pontic (Black Sea) and Caspian species. However, the zebra mussel has been accidentally introduced to numerous other areas, and has become an invasive species in many different countries worldwide. Zebra mussels get their name from a striped pattern which is commonly seen on their shells, though it is not universally present. They are usually about the size of a fingernail, but can grow to a maximum length of nearly 2 in (5.1 cm). Shells are D-shaped, and attached to the substrate with strong byssal threads, which come out of their umbo on the dorsal (hinged) side.

They remove particles from the water column. The zebra mussels process up to one liter of water per day, per mussel. Some particles are consumed as food, and feces are deposited on the lake floor. Non-food particles are combined with mucus and other matter and deposited on lake floors as pseudofeces. Since the zebra mussel has become established in Lake Erie, water clarity has increased from 6 inches to up to three feet in some areas. This improved water clarity allows sunlight to penetrate deeper, enabling growth of submerged macrophytes. These plants, when decaying, wash up on shorelines, fouling beaches and causing water quality problems.
