collected, are shown in both figures. Data available
for surface-water-quality sites include continuous
streamflow; field properties (water temperature, specific
conductance, dissolved oxygen, pH, and alkalinity);
major ions; nutrients; pesticides; dissolved and
suspended organic carbon (DOC and saC); suspended
sediment; VOCs; trace elements; and algae, macroin-
vertebrate, and fish communities. Sampling media for
the various chemical constituents are water, bed sedi-
ment, fish tissues, and macroinvertebrate tissues.
Figure 7 shows the distribution and period of record
for surface-water nutrient samples. Nutrient data were

collected at 30 sites in the Gore Creek watershed, but
only 9 sites had more than 5 nutrient samples. Figure 8
shows the distribution and period of record for surface-
water trace-element samples. Trace-element data were
collected at 30 sites, and only 12 sites had more than
5 trace-element samples.
Ground-water sampling sites are listed in table I
(sites 67-72) and are shown in figure 9. Five ground-
water-monitoring wells (sites 67 and 69-72) were
completed in the unconsolidated alluvium and were
sampled as part of an urban land-use study conducted
by the USGS. Ground-water site 68 is a three-well
