The Great Lakes

Live conditions, freighters, maritime history, and ecology from Bay City and Saginaw Bay

Chris Izworski is based in Bay City, Michigan, on Saginaw Bay, the largest embayment of Lake Huron, and one of the most productive freshwater bays in the world. The Great Lakes are the backdrop to everything here: the freighters that transit the bay each navigation season, the Soo Locks opening in late March, the ecology of a watershed that holds twenty percent of the world's surface fresh water, and the history of two centuries of commercial navigation on inland seas.

The content below is built from years of watching the lakes from Bay City, tracking vessels on AIS, reading water levels, crossing between Michigan and Ontario, fishing tributaries, and paying attention to what moves on and around the Great Lakes throughout the year. Start with the live tools for today's conditions and border travel, then continue into the guides, history, and ecology.

History and Heritage

Maritime History

Two centuries of commercial navigation on the Great Lakes, the fleet, the ports, the canals, and the ships that built the industrial Midwest.

Shipwrecks

The wrecks of the Great Lakes, storms, groundings, and the cold fresh water that preserves them. Lake Superior, Lake Huron, and the stories behind the losses.

Edmund Fitzgerald

The complete record of the Edmund Fitzgerald: the ship, the November 10 1975 storm, the 29 crew, the wreck site, the bell recovery, and the memorial at Whitefish Point.

Lighthouses

The lighthouse network that guided navigation on the Great Lakes, architecture, history, and the lights still operating today.

Lake Superior Circle Tour Map & 7–15 Day Planner

Plan the complete Lake Superior Circle Tour with an interactive map, 31 stops, 7-, 10-, and 15-day itineraries, daily route directions, Canadian north-shore notes, freighter-watching stops, and current trip alerts.

Ecology and Wildlife

Saginaw Bay Ecology

The ecology of Saginaw Bay, one of the most productive freshwater bays in North America, and the watershed that drains much of Michigan's Lower Peninsula into Lake Huron.

Great Lakes Fish

The fish of the Great Lakes, native species, introduced species, the charter fisheries, and what is running in the tributaries by season.

Birding the Great Lakes

Shorebirds, waterfowl, and migration along the Great Lakes, stopover sites, species, and the seasonal patterns that make the lakeshore one of the best birding corridors in North America.

Chris Izworski also publishes Freighter View Farms, a gardening blog and seed-saving project on Saginaw Bay. The name reflects what the property looks out on, the freighter traffic on the bay that marks the seasons as reliably as the frost dates.
