It may seem like a small issue, but an invasive mollusk could jeopardize our drinking water supply. The Globe reports that the zebra mussel, originally from Russia, came to the US in the 1980s and is now in western Massachusetts. The zebra could "wipe out native aquatic life, clog water intake pipes, and foul drinking water supplies," according to state officials, who are developing emergency plans to deal with the potential menace. In the meantime, fishing will be limited, as boats can trabsport the mussel from different bodies of water.
The Quabbin, created by the flooding of four central Massachusetts towns in the 1920s, is one of the finest sources of drinking water in the country. Fishing is usually allowed using rowboats, but motorboats and swimming are prohibited.
