The dictionary-de is generated from igerman98, using the generated hunspell/de_DE.{dic,aff}. In those, "Hochwasser" (flooding, literally high water) is handled as compound of "Hoch" und "Wasser". This can be tested by calling hunspell on the dic/aff files manually and verifying that it doesn't parse Hochwasser as an error. However, hunspell-spellchecker thinks "Hochwasser" is an error.
