Table 2. Suspended-sediment concentrations and associated turbidity during storm sampling in the McKenzie River basin, Oregon, 2003–04.
[Samples excluded from regressions between suspended-sediment concentration and turbidity were those where turbidity was less than 0.9 FNU or was not available. No regression was performed for the McKenzie River at Hayden Bridge because not enough samples were collected. Abbreviations: ft3/s, cubic foot per second; FNU, formazin nephelometric units; SSC, suspended-sediment concentration: mg/L, milligram per liter; mm, millimeter; N/A, not available; <. less than; *, sample was used in regression]
