Flooded areas beyond established mapping

English: During flooding episodes, areas may be flooded even though the cartography established does not indicate that they are located in flood zones. This situation can occur when the water levels reached exceed those represented on the map or when floods affect areas that have not yet been studied. These cartographic data correspond to the delimitation of these territories and are used to produce event maps of these floods. To date, the following sectors have been maped: * Lac-Saint-Jean (2022) * Lac-Saint-Jean (2022) * Saint-Maurice River (2022) Photogrammetric capture, allowing the delimitation of these territories, was carried out following the farthest limit reached by the waters from aerial photographs taken during the floods. It should be noted that this work is part of measure 4 of __ [Plan for the protection of the territory against floods (PPTFI)] (https://www.quebec.ca/gouvernement/politiques-orientations/plan-de-protection-du-territoire-face-aux-inondations)__.This third party metadata element was translated using an automated translation tool (Amazon Translate).
