Monitoring sites were identified near the mouths of major tributaries, upstream and downstream of major reservoirs, and at additional locations on the main-stem rivers. These sites completed the surface-water monitoring network and assured a more complete spatial coverage than the sampling sites described above could provide alone. Synoptic surveys of the entire monitoring network were conducted three times during the period of study (June 1993, March and May 1994). Surveys were conducted during spring and early summer to coincide with periods of nutrient and pesticide applications to urban and agricultural lands.
