* For 1975-1997 data, samples that were not collected are represented with a negative nine value (e.g. –99.99, -9.99, -999) or 99.9 for water temperature. This data has the Laboratory, Method Detection Limits (MDL) applied. Raw data values below the MDL appear as the MDL value.
All data should be considered provisional.
