Abstract

During the 1998-1999 biennium, as part of the Texas Natural Resource Conservation Commission (TNRCC) Clean Rivers Program (CRP), the Houston-Galveston Area Council (H- GAC) and the U.S. Geological Survey (USGS) initiated a cooperative study to characterize baseline water and sediment quality conditions in Christmas Bay. For this project, a continuous water quality monitor was installed in Christmas Bay. Data collected at this station were water stage, rainfall, wind direction, wind speed, water temperature, dissolved oxygen, pH, specific conductance, and turbidity. In addition, water-samples were collected monthly (February 1998 through January 1999) from Christmas Bay and two secondary bays, Drum and Bastrop. These monthly samples were analyzed for concentrations of selected chemical constituents, including nutrients, major ions, trace metals, chlorophyll, and suspended sediment. During the month of April 1999, water samples were also collected from each of the three bays and analyzed for selected pesticides. Samples of bottom sediment were collected from each of the three bays in November 1999, and sent to the laboratory to be analyzed for selected pesticides.
