The Detroit River is about 32 miles long from its head at the Windmill Point Light to its mouth at the Detroit River Light in Lake Erie. The fall in water level from Lake St. Clair to Lake Erie, about three feet. The river is characterized by two distinct reaches. The upper reach extends downstream from Lake St. Clair to the head of Fighting Island, about 13 miles. As water flows out of Lake St. Clair, it divides as it passes Peach (Peche) Island. The channels on both sides of this island are relatively deep, but the main navigation channel from Lake St. Clair lies north of this island. Just below Peach Island lies Belle Isle. The main river channel, the Fleming Channel, runs to the south of this island. The channel north of Belle Isle is divided by the Scott Middle Ground, over which depths vary from 1 to 6 feet. The channels on either side of the Scott Middle Ground are quite deep (19 to 30 feet), but are only used by small craft.
