Table 2

Water-quality parameters measured during the 1994 summer sampling season.

[Sites 3, 5, 7, 8, 11, 16, 17, 19, 21, 24, 27, 28, and 31 were not sampled during the period. Sites 2, 14, and 25 were each sampled twice during the sampling period. Numbers in brackets are USGS National Water Information System (NWIS) parameter codes. hh, hours; id, identification; mg/L, milligrams per liter; mm, minutes; mm/dd/yyyy, month/day/year; na, not analyzed; °C; degrees Celsius; μS/cm, microsiemens per centimeter]
