Summary statistics and graphical comparisons of specific conductance, temperature, and dissolved oxygen data, Buffalo Bayou, Houston, Texas, April 1986 - March 1991
MetadataShow full item record
Buffalo bayou is the major stream that drains the Houston, Texas metropolitan area. The U.S. Geological survey has provided specific conductance, temperature, and dissolved oxygen data to the city of Houston for three sites along a 7.7 mile reach of buffalo bayou since 1986. Summary statistics and graphical comparisons of the data show substantial variability in the properties during 1986-91. Specific conductance ranged from about 100 microsiemens per centimeter at 25 degrees Celsius at each of the three sites o 17,100 micosiemens per centimeter at 25 degrees Celsius at the most downstream site, at the headwaters of the Houston ship channel. Water temperatures ranged from 5 to 33 degrees Celsius. Temperatures were very similar at the two upstream sites and slightly warmer at the most downstream site. Dissolved oxygen ranged from zero at the most downstream site to 11.7 milligrams per liter at the most up stream site.
