The Saginaw River is formed by the confluence of the
Tittabawassee and Shiawassee Rivers at Green Point at the south limit of the
city of Saginaw. The river flows north
for 22 miles and empties in the head of Saginaw Bay. The lower 18 miles of the river form a commercial harbor. Grain, chemicals, petroleum products,
limestone, coal, sand, gravel, and cement are the major commodities handled at
the ports of Bay City, just north above the river mouth, and Saginaw, 19 miles
above the river mouth.
The Great Lakes Towing Company provides towing service in
Calcite with its tugs from Sault Ste. Marie.
24-hours minimum notice and/or service in Calcite is required
when placing an order for tug service.
Calcite is a private harbor owned and operated by Michigan
Limestone Operations for shipping limestone.
The harbor is protected on the northwest and north by a point and
breakwall and to the southeast by Quarry Point. The harbor affords no shelter from north to east winds except for
small craft, which can enter the tug basin on an emergency only basis.
Calcite harbor is subject to fluctuations of water level. A water gauge on the southwest corner of the
tug basin, lighted at night, shows the maximum depth to which vessels may be
loaded and should be checked by vessel masters.
