It is assumed <br />that the depletion caused from pumping this water from the Duckworth Pit is offset by "recharging" the Silt Ponds. <br />Therefore, since the Duckworth Pit and silt ponds aquifer parameters are approximately the same, no depletion is <br />(3) Water pumped from dewatering trenches into the Smith & Emmons Ditch.
