Upper Basin Diversion Channel, Plate 1, will be revegetated <br />along its entire course. (Top and subsurface soils not used in <br />channel reclamation will be stocl~iled from the construcCion of <br />this Channel for use in other areas during final reclamation and <br />abandonment.) Side slopes (2:1) of the Channel will be fertilized <br />and seeded with seed mixture ~p3*, hydraulically. Additionally, <br />jute mesh will be placed to prevent major erosion during the <br />establishment of the vegetative ground cover. Native plant materials <br />will be added above the flow line after establishment of the base <br />vegetation.
