| Summary: | Monitoring water quality is a major issue on California's rangeland watersheds, and
there is limited published data to guide these efforts. We used stream-flow and water-quality
data from experimental rangeland watersheds to demonstrate the temporal variability
of water quality at the storm, season and annual time scales. The timing and frequency
of water sampling from the storm to the annual time scale play an extremely significant
role in water-quality monitoring. Our studies conducted in Northern California suggest
that a minimum sampling strategy should include sampling before, during and after
storms. Samples must be collected over a period of several years to account for variability
among years. |
