Zebra mussels are filter feeders they take in water and remove what food they want. Waterways around the Sierra Nevada mountains may have insufficient calcium (an element needed for shell growth) and some lakes in northeast California may be too salty for mussel survival.

While these animals have had an individual presence on the river for a number of years, a reproducing population had never been discovered on the St. Croix. A more conservative study estimated total economic costs of $267 million for electric-generation and water-treatment facilities in the entire United States from 1989 through 2004.
