ZURICH - City crews and VBZ reopened most of the lake-basin tram routes on Sunday morning after the Street Parade. Cleaning ran from the Enge dam back toward Utoquai. A few barriers stayed until noon for trucks that still had to collect staging.

Shopkeepers on Bellevue called the night loud and the morning punctual, which is the deal they have made with this Saturday for years. Lost-property desks opened early.

Basel was preparing its own water party on the Rhine the same day. Switzerland's August is a series of permitted crowds. The permits matter.
