Banks, even though they be private property under a former law or custom, are subject throughout their entire length, and margins for a zone of three meters, to a right of way for public use in the general interest of navigation, the floating of logs or rafts, fishing, and salvage.Nevertheless, when the topography of the land or other legitimate causes should so require, the zone of this right of way shall be widened or reduced and all interests conciliated in so far as possible.The regulations will set forth when, in what cases, and in what form the distances prescribed in this section may be changed. History —Law of Waters, art. 36.
