Lake Erie's Great Lakes Neighbors: Geography Clarified

Erie, Pennsylvania sits on the southern shore of Lake Erie itself — it doesn't have another Great Lake "next to it." The Great Lakes chain is linear west-to-east:

The Great Lakes Sequence

1. Lake Superior (westernmost, largest, deepest)
2. Lake Michigan (entirely US, connected to Huron by Straits of Mackinac)
3. Lake Huron (includes Georgian Bay, North Channel)
4. Lake St. Clair (small, connects Huron → Erie via Detroit/St. Clair Rivers)
5. Lake Erie (shallowest, warmest, southernmost)
6. Lake Ontario (easternmost, smallest surface, deepest average — receives Erie via Niagara River)

Lake Erie's Direct Connections

• Inflow: Detroit River (from Lake St. Clair / Huron) — 80–90% of water.
• Outflow: Niagara River → Niagara Falls → Lake Ontario.
• Basin: 58,800 km² (smallest Great Lakes watershed).

Erie, PA Context

• Presque Isle: 11 km recurving sand spit — creates Presque Isle Bay (harbor).
• Distance to other lakes: Lake Ontario ~150 km (via Niagara); Lake Huron ~200 km (via Detroit R.); Lake Michigan ~350 km.
• Not on: Lake Ontario (that's Rochester, Oswego), Lake Huron (Port Huron, Sarnia).

Why the Confusion?

People know "Great Lakes" as a set but not their order. Erie is the fourth in the chain — between Huron and Ontario. Pennsylvania touches only Lake Erie among the Great Lakes.
