[Talk-ca] Proposed river cleanup in Canada

[Pierre-Léo Bourbonnais]

Oui, j’ai effectivement trouvé plusieurs ruisseaux complètement obsolètes (qui n’existent plus et ont été soit détournés soit remblayés). Il manque aussi plusieurs “tunnels” sous les routes et sous les chemins de ferme.

Yes, I also found multiple obsolete streams that I removed because they were either dried out for fields or displaced. There are also a lot of missing tunnels under roads and agricultural tracks.

I aslo realigned the shorelines on Ile Perrot and around the river in Drummondville, but it is an intensive task. We would need a lot more human ressources to be able to realign more regions.

C'est un problème important, et encore plus dans les régions peu habitées du nord où il y a eu des imports Canvec de mauvaise qualité.  On retrouve parfois des doublons, aussi doublons cours d'eau + forêts. Et en plus des inochérences, empiètements, etc.
