      It looks like -au basically traces the Elbe basin, so I assume that that ending took over in that area for some reason

      It might be -beek and -bek, due to Lower Saxon (Plattdeutsch) influence. -bruch/-bruck and -brück might also be relevant.

        Not might, it is this. -bruch, -bruck and -brück are something different though. While being related to the english “brook”, a Bruch is swampland. -bruck or -brück however indicate a bridge (like the German word for bridge, Brücke).
