USGS Water-Year Summary 2019
08074710 Buffalo Bayou at Turning Basin, Houston, TX
LOCATION - Lat 29°44'57", long 95°17'27" referenced to North American Datum of 1927, Harris County, TX, Hydrologic Unit 12040104, on left bank at Wharf No. 5 at end of private road, 1.8 mi upstream from Brays Bayou, and 4.9 mi east of downtown Houston.
DRAINAGE AREA - 465 mi².
PERIOD OF RECORD - Jan. 1987 to Sep. 2009 (daily maximum, minimum, and mean gage height). Oct. 2009 to current year (daily maximum and minimum gage height). PERIOD OF RECORD, Water-Quality.-- CHEMICAL DATA: Jan. 1998. BIOCHEMICAL DATA: Jan. 1998. BIOLOGICAL DATA: Jan. 1998. PERIOD OF DAILY RECORD, Water-Quality.-- SPECIFIC CONDUCTANCE: Apr. 1986 to Sept. 2005. pH: July 1998 to Sept. 2005. WATER TEMPERATURE: Apr. 1986 to Sept. 2005. DISSOLVED OXYGEN: Apr. 1986 to Sept. 2005.
GAGE - Water-stage recorder. Datum of gage is National Geodetic Vertical Datum 1988, 2001 adjustment. Prior to Oct. 1, 2016, datum of gage is NGVD of 1929, 1978 adjustment, (0.296 ft above current datum) unadjusted for land-surface subsidence. Satellite telemeter at station.
REMARKS - Astronomical tides cause significant cycles of approximately 24.84 hours at this site. Because a different portion of the 24.84 hour tidal cycle is averaged in successive daily (24-hour) computations, a systematic secondary oscillation, unrelated to basin hydrology and having a period of about two weeks may be apparent in daily data published from Jan. 1987 to Sep. 2009. Only very large storms or hurricane surge produces elevations above normal tidal fluctuations. Some records listed in the "Period of Record" for surface water and water quality may not be available electronically.
EXTREMES FOR PERIOD OF RECORD - Maximum elevation, 14.76 ft, Sept. 13, 2008 (Hurricane Ike); minimum, -3.2 ft, Sept. 24, 2005. (at previous datum).
PERIOD OF DAILY RECORD - SPECIFIC CONDUCTANCE: Apr. 1986 to Sept. 2005. pH: Oct. 1998 to Sept. 2005. WATER TEMPERATURE: Apr. 1986 to Sept. 2005. DISSOLVED OXYGEN: Apr. 1986 to Sept. 2005.
INSTRUMENTATION - Water-quality monitor Apr. 1986 to Sept. 2005.
REMARKS - Records for specific conductance, water temperature and pH are good. Record for dissolved oxygen poor. Water-quality monitor data have been collected one ft below the water surface since Feb. 3, 1998. From Apr. 1986 to Jan. 1987 data were collected at a fixed elevation of 6.5 ft below sea level using a submersible pump. From Feb. 1987 to Jan. 1988 data were collected at a fixed elevation of 5.5 ft below sea level using a submersible pump. Dissolved oxygen data are not corrected for salinity. Prior to Sept. 1995, the upper limit of the specific conductance instrument was 20,000 microsiemens/cm. Due to tidal effects, location of probe units, and channel morphology, the water-quality data collected at this location may not be representative of the entire flow through the cross-section.
EXTREMES FOR PERIOD OF DAILY RECORD - SPECIFIC CONDUCTANCE: Maximum, >20,000 microsiemens/cm, Oct. 12, 13, 14, Dec. 13, 1988, Jan. 23, 1989; minimum, 60 microsiemens/cm, June 26, 1989. pH: Maximum, 8.6 standard units, June 9, 2001; minimum, 6.3 units, Feb. 25, 26, 2003. WATER TEMPERATURE: Maximum, 36.5°C, Aug. 21, 1990; minimum, 7.0°C, on Jan. 13, 14, 1997. DISSOLVED OXYGEN: Maximum, 20.0 mg/L, June 6, 1996; minimum, 0.0 mg/L, on several days during 1987-88 water year.
