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.
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.
