  1. The Future of the Suwannee River SillA Review and Update S.B. Aicher – USFWS, Okefenokee NWR

  2. Downstream Flows Water Quality Ground-water levels

  3. Effects of the Sill Downstream • No significant changes in ground-water levels at wells downgradient.

  4. Calcium Chloride Iron Magnesium Silica Sodium Tannin and lignin Solids residue Strontium Zinc

  5. Effects of the Sill Downstream • No significant changes in ground-water levels at wells downgradient. • No significant change in concentrations of water-quality constituents in flows at the sill.

  6. Effects of the Sill Downstream • No significant changes in ground-water levels at wells downgradient. • No significant change in concentrations of water-quality constituents in flows at the sill. • The sill increased the base water levels immediately upstream of the sill by 6 ft.

  7. Effects of the Sill Downstream • No significant changes in ground-water levels at wells downgradient. • No significant change in concentrations of water-quality constituents in flows at the sill. • The sill increased the base water levels immediately upstream of the sill by 6 ft. • No significant changes in water levels downstream from the sill.

  8. Effects of the Sill Downstream • No significant changes in ground-water levels at wells downgradient. • No significant change in concentrations of water-quality constituents in flows at the sill. • The sill increased the base water levels immediately upstream of the sill by 6 ft. • No significant changes in water levels downstream from the sill. • The sill decreased the peak flows from the sill to Fargo, Georgia.

  9. Effects of the Sill Downstream • No significant changes in ground-water levels at wells downgradient. • No significant change in concentrations of water-quality constituents in flows at the sill. • The sill increased the base water levels immediately upstream of the sill by 6 ft. • No significant changes in water levels downstream from the sill. • The sill decreased the peak flows from the sill to Fargo, Georgia. • The sill increased the base flows downstream as far as Blue Sink.
