Remove, at no additional cost to the Department, the silt, etc., as often as necessary to avoid polluting the downstream area. 2. When roadway work progresses enough that a normal stand of grass can prevent erosion and pollution of the l ake, excavate and clean the lake of foreign matter. Return the lake to the original contour and condition or proposed contour, if different than the original. 3. Dispose of material removed in a manner satisfactory to the Engineer. 4. After removing the deleterious materials from the lake, grade and grass disturbed areas not under water. B. Alter Lakes or Ponds If alteration is shown as a Pay Item, work shall include activities to change the physical size, shape, or depth of the l ake; or to change the high-water level, or elevation of the dam or portions of it.
