Photo captured October 29, 2019; view to the west-southwest. <br /> Once it was determined that the sump had risen almost a foot within the hour following <br /> initiation of flushing, it became immediately apparent that pumping needed to begin <br /> promptly. (This realization nullified the previous hypothesis that no flow would result <br /> from pumping water through the road fill.) Constant pumping efforts were initiated and <br /> ceased only when the hoses were transferred between tanks as they were filled. After two <br /> hours of pumping, it was determined that flow into the sump was occurring at a rate of <br /> 5,000 gallons an hour based on the amount of water collected in the tanks located on the <br /> haul road. <br /> 22 <br />
