Intensive Survey of the Guadalupe River Segment 1806

METHODS
Field and laboratory procedures used during this survey are described in
Appendix A. The field measurements, water chemistry, hydraulic, and
biological data were collected November 1-3, 1983, by the Texas Water
Commission (predecessor agency, Texas Department of Water Resources),
Water Quality Assessment Unit personnel with assistance from Texas Water
Commission District 8 personnel in San Antonio. Laboratory analyses of water
samples were conducted by the Texas Department of Health Chemistry
Laboratory in Austin, Texas. Bacteriological analyses were conducted by the
the Upper Guadalupe River Authority. Benthic macroinvertebrate samples
were collected by Jack R. Davis at selected stations on November 2-3, 1983,
and returned to the Water Quality Assessment Unit's laboratory for identifi
cation and enumeration. Parametric coverage, sampling frequencies and
spatial relationships of sampling stations were consistent with the objectives of
the survey and with known or suspected forms and variabilities of pollutants
entering the stream.
