Lake Champlain International

Lake Champlain is about to get a little cleaner. A new boat — a sort of waterborne honey-wagon — that collects sewage from boaters' tanks was christened yesterday in Burlington.

It’s pouring rain at the Burlington waterfront. But that doesn’t stop about 20 people from coming to watch the launch of Lake Champlain’s newest service boat.

It’s called Champlain’s Ark. And its job isn’t pretty: hauling and disposing human waste so boaters don’t empty their tanks directly into the lake.

James Ehlers, director of Lake Champlain International, says it's a challenge.
