Water budget for the Nueces Estuary, Texas, May-October 1998
The Texas Water Development Board (TWDB), Texas Parks and Wildlife Department (TPWD), and Texas Natural Resource Conservation Commission (TNRCC) are charged by the Texas Legislature with determining freshwater inflows required to maintain the ecological health of streams, bays, and estuaries in Texas. To determine required inflows, the three agencies collect data and conduct studies on the needs f

Hydrologic conditions and water quality in an agricultural area in Kleberg and Nueces Counties, Texas, 1996-98
During 1996?98, rainfall and runoff were
monitored on a 49,680-acre agricultural watershed
in Kleberg and Nueces Counties in South Texas.
Nineteen rainfall samples were analyzed for
selected nutrients, and runoff samples from 29
storms were analyzed for major ions, nutrients, and
pesticides. Loads of nutrients in rainfall and loads
of nutrients and pesticides in runoff were computed.

Stormwater runoff for selected watersheds in the Edwards Aquifer recharge zone, Bexar County, Texas, 1996-98
The Edwards aquifer is one of the most productive carbonate aquifers in the Nation. The dissolution-modified, faulted limestone aquifer is the sole source of public water supply for San Antonio, Texas (fig. 1) and is the major source of water for Bexar County. In addition to providing public water supply to more than 1 million people, the Edwards aquifer supplies large quantities of water for agri

Discharge measurement in tidally affected channels during a hydrographic estuarine survey of Sabine Lake, Texas
A hydrographic survey of Sabine Lake, a broad, shallow estuary lying on the Texas-Louisiana border, was conducted in June 1996 to help address questions relating to potential environmental effects of future water demands in Texas. The use of a variety of new instruments in this study is one means by which automation is improving efficiency and effectiveness of these efforts by increasing the quali
