Dredging is required to remove the sedimentation that is constricting the intakes from diverting water. While all three of the pumps are affected, sedimentation only needs to be removed upstream of the second and third pump intakes. If the sedimentation is not properly removed, the pump intakes cannot function correctly and deliver water to the existing crops. The dredging plan includes removal of approximately 3,000-5,000 cubic yards of sedimentation. This includes dredging approximately 200 feet upstream from the third pump intake and approximately 100 feet upstream of the second intake pump. Dredging will occur by use of a dragline excavator bucket system and will not impact the existing levees or vegetation.
