Water was being pumped into the water storage tank <br />and overflowing through a plastic pipe into Pond 001. <br />Pond 001- east segment 6 is a rubber lined ditch. The ditch has a significant amount of sediment that needs to be <br />removed (photo 1). <br />Pond 001- east segment 7 is not configured as outlined on Map 2.05.3(4) -7. At location 26 +75, the geo -web <br />under the rock is not in place high enough up the south and north side slopes for the required flow line (photo 2). <br />A second discontinuous piece of geo -web is higher on the south side bank (photo 3). Also, the typical cross <br />section of the ditch is drawn as 21.9' wide, but nowhere is this cross section seen in segment 7. The bottom of the <br />ditch is filled with 6 inches of soil and rock above the geo -web. <br />Pond 001 east ditch segments 1 and 2 are designed to be lined with geo -web as per Map 2.05.3(4) -7.
