In its original natural state, the river started at rapids formed by water from the Everglades flowing over a rocky ledge four miles (6.4 km) from its mouth. Frederick H. Gerdes of the US Coast Guard reported in 1849 that "From the upper falls to near its entrance into Key Biscayne Bay ... water in the Glades was 6 feet 2.5 inches (1.89 m) above low tide."[ The rapids were removed when the Miami Canal was dredged in an attempt to drain the wetland.
The river divided into a North Fork and a South Fork about three miles (4.8 km) above its mouth. Each fork extended only one mile (1.6 km) to rapids marking the edge of the Everglades. The North Fork had the greater flow and the higher drop over its rapids. One-and-one-half miles (2.4 km) above the mouth of the river there was a tributary on the north side, called Wagner Creek, which was about two miles (3.2 km) long. The Miami River was also fed by several springs, including some in the bed of the river. Flow was variable and in times of drought sometimes stopped completely.
