Lake Clarity Up After Zebra Mussel Invasion - Otsego Lake in New York is getting clearer these days, but that may not be as such good news as it sounds. That’s because the lake is beset with zebra mussels, an invasive species known for its filter-feeding ways that, though they may make waters clearer, strip out much of the nutrients that algae and other aquatic plants use to grow.
