Abstract: The apparatuses for improving the permeability of a fluid containment basin having a plurality of ridges and furrows in the bottom of the basin are configured to disturb sediment that has settled on the ridges so as to place the sediment back into suspension. In one configuration, the apparatus comprises a tool support frame adapted to support one or more ridge treating tools on top of the ridges. The tools can include dragging, discing and/or grinding tools that are selected to disturb the sediment on the sides of the ridges. Boats or other devices, such as tensioning cables, can be used to move the frame and tools across the basin on the ridges to disturb the sediment on the ridges. The tool support frame can be configured to be raised or lowered from the ridges as desired to alternatively move between or treat the ridges.
