Dataset Direct Download Service (WFS): Water holding structure represented by a point in the Haut-Rhin

This layer describes structures of all importance that impede the flow of a watercourse, whether in the minor bed (spikes, thresholds) or in the major bed (dams) and structures located outside the bed of a watercourse to constitute a storage of water (colline retention). A similar layer N_OUVRAGE_RETENUE_L describes the works linearly. By convention, works falling under headings 3110 1° and 2°a and headings 3250 1° and 3° of Decree 2006-881 of 17 July 2006 are classified as works of interest to public safety. Major bed embankments are treated in the N_REDUCTION_LIT_MAJEUR layer, flood protection dikes and canalised river dikes are described in the N_DIGUE_P and N_DIGUE_L layers
