River along the border between Michigan and Ontario
At the mouth it carries 5.3 m³/s on average: an Olympic pool every 470 seconds. Its basin covers 1,811 km², about the size of GP. 19.6 million people live in it. Highest water: from April to June; lowest: from January to February. Its dams hold back little of its water (7.0% of a year's flow).

Detroit River, month by month
Highest water: from April to June
Lowest water: from January to February. Freezing months (average below −4 °C): January. Best months to visit: from May to September.
From about 8,500 m³/s in the lowest month to 10,100 m³/s in the highest. An estimate: the monthly flow is modelled from the lowest and highest months of WaterGAP (RiverATLAS, 1971–2000) and the rain and snow along the river (WorldClim). Dams change the real rhythm. The chip is the average air temperature; below it, the month's rain.
