Lake Kankakee
former lake in the United States

Lake Kankakee formed 14,000 years before present (YBP) in the valley of the Kankakee River. It developed from the outwash of the Michigan Lobe, Saginaw Lobe, and the Huron-Erie Lobe of the Wisconsin glaciation. These three ice sheets formed a basin across Northwestern Indiana. It was a time when the glaciers were receding, but had stopped for a thousand years in these locations. The lake drained about 13,000 YBP, until reaching the level of the Momence Ledge. The outcropping of limestone created an artificial base level, holding water throughout the upper basin, creating the Grand Kankakee Marsh.
Lake Kankakee was a prehistoric lake during the Wisconsin glacial epoch of the Pleistocene Era. The lake formed during the period, when the Michigan and Saginaw lobes of the Laurentian glacier had receded back to the Valparaiso and Kalamazoo moraines. While the glacial advance became stagnant, the summer runoff formed a large lake covered parts of 13 counties in two states.

Why this record matters
The phrase “former lake in the United States” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Maps, plans, fabric surveys and administrative records can establish how the site’s name, extent and function changed over time. The source revision retrieved here is dated Jul 26, 2026. The linked authority identifier is Q16998086. Authority coordinates are 41.220, -86.960. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1840.
A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
