North Texas’ Barnett Shale — one of the country’s largest natural gas fields and the birthplace of modern fracking — holds even more reachable gas than previously thought, the federal government says.  

The U.S. Geological Service is still reporting earthquakes in spite on the government shutdown, and it logged one at about 8:30 Tuesday night in Ovilla, south of Dallas.

USGS reported the minor, 2.4 quake was centered off Ovilla Road, just east of Interstate 35.

Ovilla has about 3,400 residents and straddles the Dallas-Ellis county line.  Three people in neighboring Cedar Hill reported on the USGS website that they felt the teeny quake.

Less than a year after zebra mussels were found in Lake Ray Roberts, the destructive invasive species has been confirmed in Lewisville Lake by the United States Geological Survey (USGS). This is the third lake in Texas, and the second within the Trinity River basin, where zebra mussels have been discovered.
