Eventually, the drainage outlet from the entire pit will <br /> be in the center of the highwall and at the lowest point of the pit edge. Rather than a deep cut, material mostly from the rough area to <br /> the left of the low point will be used to fill in the basin and create an outlet that will be only a little bit lower than the ground on the other <br /> side of the highwall. Thus, there will be a shallow, low grade cut in the edge of the pit that connects the pit to the actual drainage outlet <br /> where it meets the undisturbed land a short ways beyond the low point of the current wall. This will allow for a smooth drainage of the <br /> pit to a drainageway a short distance to the north that originally received water from this area prior to mining. A small and shallow <br /> catchment/sediment basin will be constructed on this side of the outlet to capture sediment before it gets carried into the final <br /> drainageway. This can eventually become a small filtering wetland at the outlet. In this way, the drainage course from the south to the <br /> north of the pit will be very gradual so as to avoid higher velocity, erosive flows. It is possible that willow cuttings will be placed in and <br /> beside the channel to create a shrub lined drainageway similar to other drainages in the area. Minimal rip rap will be used as such <br /> large rocks are not characteristic of this landscape. <br />
