State Act
Section 442. Free flow of water
Article 442 – Free flow of water - The owners or possessors of properties, crossed by or adjacent to any watercourses, shall abstain from doing any act, which may obstruct the free flow of those waters, and shall remove any obstacles to such free course when such watercourses have their source in their properties, in such manner that from such acts and obstacles no damage is caused to their neighbours, either on account of stagnation or back flow of waters, or on account of their delayed flow or loss, except, in the last two cases, on account of their lawful utilization. § Sole Paragraph. When the obstacle to the free course of water does not arise in a certain marginal property or is not attributable to the owner thereof, the manner of its removal shall be regulated by administrative legislation.
