Hello. Since you are using JOSM, please add to your tools the fast Draw plug-in (https://wiki.openstreetmap.org/wiki/JOSM/Plugins/FastDraw)
You can join the Chilean community via Telegram (https://t.me/OSMcl) and I can teach you how to set it up.
it has a small learning curve and you will never draw a lake or a long path without it anymore.
regards.
