USGS field crews made multiple record high flood measurements on Aug. 27, including downstream of Addicks and Barker dam. Flood measurements near Addicks and Barker dam are critical for making public safety decisions, as 1.2 million people live downstream.

In addition to staff that conduct field measurements of flooding conditions, others monitor information indoors. Here, USGS scientist Jeff East is monitoring streamflow and flooding from Hurricane Harvey.

Marker bed known as the Loriolia Bed, found 80 feet below the contact of the Glen Rose Limestone and the Kainer Formation. The photograph was taken north of Farm to Market Road (FM) 195, approximately 1,500 feet west of the intersection of FM 220 and FM 195. The Loriolia texana fossils are identified by white arrows (photograph by Allan K. Clark, U.S.
