Officials in California are hoping Labor Day boaters will help keep invasive quagga and zebra mussels in check this Labor Day holiday weekend.

“Californians have a unique opportunity to enjoy numerous natural resources,” said California Department of Fish and Wildlife Director Charlton H. Bonham. “Doing your part to clean, drain and dry before heading out to recreate will help keep them free of quagga and zebra mussels, as well as other invasive species.”

A new scientific federal study shows groundwater in Santa Barbara County's Cuyama Valley is being depleted two times faster than it's being replenished.

Groundwater is the sole source for agricultural, domestic and municipal water in the valley during dry periods, according to the U.S. Geological Survey (USGS). 

Scientist Randy Hansen is the lead author for the USGS study and says the water quality coming from the basin is not very good to begin with and over-pumping can make it worse.
