Quagga mussels, an invasive species, popped up in California in 2007. Since then, they've spread to more than 30 bodies of water in the state, blocking drains and causing a nuisance for years. Well, last week they showed up in Pyramid Lake, north of Los Angeles, which is a big deal.
Tanya Veldhuizen is the lead scientist for the aquatic nuisance species program for the state water project and she joined Sanden Totten to talk about how they're addressing the problem.
