1Stage code:
0 = good
1 = adjusted (to agree with observer staff plate readings)
2 = interpolated; good
3 = interpolated; fair
4 = interpolated; poor

2Turbidity code:
0 = good
1 = adjusted
2 = interpolated; good
3 = interpolated; fair
4 = interpolated; poor

3 HY 1999 Estimated sediment concentration was computed from a loess (locally weighted) regression of turbidity versus laboratory sediment concentration, based on all lab samples from hydrologic year 1999. HY 2000 Estimated Sediment concentration was computed from a linear regression of Turbidity versus laboratory sediment concentration, based on all lab samples from hydrologic year 2000.
