It ran from its head on the north or California) bank of the river, from the main channel, that at that time ran two or three miles northwest and then east of Fort Yuma.
The slough rejoined the river at its mouth nearly a mile west of Fort Yuma.
The slough would have flooded in the high water months of May and June and then been planted with crops as the water receded, the common practice of the native people along the Colorado River.
In January 1900, the Mohave II, stripped of its machinery, was run into the slough and left to decay.
A remnant of it at its mouth, remains as an inlet on the north bank of the river across from Yuma, Arizona at 32°43′50″N 114°37′45″W / 32.73056°N 114.62917°W / 32.73056; -114.62917.
