Document Description
As part of the assessment of the source of water that exits the Magenta Drain Portal, a dye tracer test is planned to determine if upstream surface water is entering the Magenta Drain Tunnel via subsurface percolation. The test consists of introducing a measured quantity of non-toxic dye into the stream channel above the Portal exit. This is the area where the flow in the stream channel disappears into the subsurface and may be percolating into the Magenta Tunnel.
