(1)-(4). [Repealed. Act June 3, 1976, No. 136, p. 390, section 25, eff. June 3, 1976.]
(5) The beds of flowing waters, continuous or intermittent, formed by rain water, and those of brooks crossing tenements which do not belong to the public domain.
In every drain or aqueduct, the water, the bed, the sloping bank, and the sideways are considered as an integral part of the tenement or building for which the waters are intended. The owners of tenements through which, or along the boundaries of which the aqueduct passes, cannot allege ownership over the same nor any right to profit by its beds or sideways, unless they base their claims on title deeds, specifying the right or the ownership claimed by them.
