Brief history and etymology
In 1856 the town of Dresden, approximately one mile east of the present town of Deep River, was platted. The Whitney brothers operated a store there for about 20 years. When the Chicago and North Western Railway was built, the residents of Dresden moved to be near the railroad, and thus the town of Deep River was established in 1884. The Dresden Cemetery lies about a mile and a half south of the current county road, locally known as the Diamond Trail, just about a quarter mile east of Iowa Highway 21. The town of Tilton was established at the southern border of the township in 1884 as well, although this largely lay in Keokuk County.

Deep River Township
Deep River Township was organized March 7, 1857. It was, at first, a part of Jackson Township. It derived its name from the stream flowing through its northern part, but not because the water was so deep, but rather it was so far down to the water. The first settlers to live in Deep River Township were Robert Taylor and family from Ohio; John Sargood, whose father was from England; Albert Morgan and family from Ohio; and the Lights, who came from Virginia in 1849. The first post office was established in 1852, and called Deep River. The first marriage was that of Nancy Taylor to Rev. W. H. Palmer in 1849. James Light and James Rundle settled in that same year.

The first township election was held in 1857 with the following officers: Ephraim Cox, Asa Cohoe and John Morgan, trustees; Myron Whitney, clerk; L. Mayo, C. M. Wolcott, justices of the peace; H. Armstrong and C. Barber, constables; and James Hillman, road supervisor.

Town of Deep River
The town of Deep River was incorporated in the summer of 1887 after the Northwestern Railroad spur from Belle Plaine to Muchakinock in southern Iowa was built. Horace Phelps built a depot and gave the railroad $1,500 to secure the location there. The citizens of Dresden then soon followed and the new town of Deep River grew, leaving Dresden largely uninhabited. The first town election resulted in the following officers: J. S. Potter, Mayor; S. S. Jenkins, recorder; J. C. Sanders, treasurer; C. F. Cutler, assessor; James Sargood, marshal; A. C. Converse, Charles Lacher, N. M. Valentine, J. P. Sargood, E. T. Whitney and James Light, councilmen.

The Deep River flows nearby; it is a minor tributary of the English River. The town and its namesake river were named not for the depth of the water in the Deep River, but for the depth of the ravine through which it flows. At some places the banks are 20 ft above the normal water level.

On May 14, 1970, the local area was subjected to a significant flood on the Deep River which was assessed as having a greater than 50 year recurrence interval. The stream gauge on the Deep River station measured a record stage of 83.85 ft and with a stream flow of 6200 ft3/s

Education
Deep River is mostly within the Montezuma Community School District and partially in the English Valleys Community School District.

The community was previously located within the Deep River–Millersburg Community School District (DR-M), which was established in 1958 as a consolidation of the Deep River and Millersburg school districts. In 1992 the district closed its secondary school and began a joint whole grade-sharing program with the English Valleys district and that of the Montezuma, in which it sent its junior and senior high school students to both districts; each student chose which secondary school to attend. The Deep River grade school was closed that year, with elementary school students moved to Millersburg, as the district found the layout of the latter more useful. On July 1, 2009, the DR-M district was consolidated into the English Valleys district, although a portion of it was given to the Montezuma district.
