Impact of Glaciation
The Wisconsin glaciation period left behind a large number of kettles, ponds, and bogs. The headwaters and upper reaches of the Portage River once contained countless examples of post-glacial wetlands. Farmers built drainage ditches to dry out many of the wetter flatlands for arable cropland, and significant population growth south of Kalamazoo has led to further alterations in the landscape. Many of the larger glacial lakes remain:
- Austin Lake, in Portage, is the largest lake in the Portage River drainage.
- Gourdneck Lake, near Portage, is so called because its unusual shape is said to resemble a mature gourd.
- Indian Lake is the site of a longtime campsite of the Potawatomi tribe of Native Americans.
- Portage Lake in St. Joseph County (not the source lake in Kalamazoo County with the same name) covers 510 acres (2.1 km2).
