Cedar Bayou is the discharge site for U.S. Steel Company, and the intake site for Houston Lighting and Power Company's Cedar Bayou Generating Station. Trinity Bay, near Point Barrow, is the discharge site for thermal effluents from the power plant. Intake and discharge canals and channels, and a 1,052.2 hectare cooling pond were built in the study area. Water was circulated for cooling at the power plant for the first time in September 1970, reversing flow in the lower 12.9 kilometers of Cedar Bayou. Thermal effluents were discharged for the first time in November 1970 when electrical power generation was begun.ecologypower plantsindustrial wastescanalscooling pondscooling waterblue crabbrown shrimpwhite shrimpgulf menhadenAtlantic croakersand seatroutpower plantssheepshead minnowGulf killifishtidewater silversidefrequencyabundancefloodingtemperaturedissolved oxygen (DO)turbiditybay anchovydensityvegetationsalinity gradientswater qualityTechnical Report
