Table 1. Summary of environmental variables measured at Barton Springs from USGS site 08155500.
Means were computed from daily statistics for each sampling interval. The grand mean and pooled range are summary statistics for the sampling interval means (i.e., the covariate values used). The total range represents the range of all daily statistics.
| Variable | Grand Mean ± SD | Pooled range | Total range |
|---|---|---|---|
| Flow (ft3/s) | 86.3 ±26.5 | 41–123 | 26–131 |
| Change in flow (ft3/s) | 4.05 ±27.1 | −31.3–2.8 | NA |
| Dissolved oxygen (mg/L) | 6.06 ±0.366 | 5.38–6.64 | 4.80–7.50 |
| Turbidity (FNU) | 2.30 ±0.510 | 1.72–2.52 | 0.8–31.4 |
| Temperature (°C) | 21.2 ±0.453 | 20.4–21.9 | 18.6–22.7 |
