Characteristics of Water-Quality Data for Lake Houston, Selected Tributary211 Inflows to Lake Houston, and the Trinity River near Lake Houston (a Potential 211 Source of Interbasin Transfer), August 1983-September 1990

摘要

This report deals only with phase I of the investigation and is a summary of211u001ewater-quality data collected August 1983--September 1990 in Lake Houston, its 211u001emajor tributaries, and the Trinity River. Summary statistics of water-quality 211u001edata collected are presented. Longitudinal profiles through Lake Houston of six 211u001eselected physical properties and chemical constituents illustrate how water 211u001equality varied vertically and along the length of the lake. Seventeen of 59 211u001eproperties and constituents collected in the sampling program were selected as 211u001eimportant factors affecting biological, physical, and chemical processes in 211u001ewater. The 17 properties and constituents were grouped on the basis of six 211u001elocations representing the study area (the lake nearest the dam, East Fork of the 211u001elake, West Fork of the lake, the eastern and western tributaries, and the Trinity 211u001eRiver), statistically summarized, and compared to available drinking water 211u001estandards established by the U.S. Environmental Protection Agency (EPA). The 17 211u001eproperties and constituent concentrations are presented in boxplots and subsets 211u001eof 13 to 15 properties and constituent concentrations statistically tested for 211u001edifferences on the basis of combinations of season, depth, location, and 211u001estreamflow.
