Traveling downstream from Brook Trout Lake, the Indian River picks up the Cobblestone Creek coming in on its left, just before it forms the Green Stillwater, a 1/2 mile long flatwater section at the base of Indian Mountain.

After this, the outlet of Mountain Lake joins the Indian River from the left, only 50' below what once was the first crossing of the river, a log bridge that loggers constructed back in the 1960s, in order to bring their logs out to market from the deep woods.

The bridge was destroyed by authorities in the 1970s, about when the Indian was declared a wild river by the New York State Department of Environmental Conservation.

Now the river again drops down a series of rapids, and picks up the outlet to Horn Lake and Ice Cave Creek, both from the left, as it bends around right.

It soon is joined by the outlet of Beaver Lake, past a few short rapids in the backwoods, and past a small island before converging with the South Branch Moose River, a mile or so above Rock Dam.
