Deep Fork of the Canadian River
The Deep Fork River (Deep Fork of the North Canadian) is an Oklahoma tributary of the North Canadian River. The headwaters flow from northern Oklahoma City and the river empties into the North Canadian River, now impounded by Lake Eufaula.
The Deep Fork begins in the storm sewers of northern Oklahoma City and flows eastward through Oklahoma County where five miles of the river is impounded by Arcadia Lake. Below the lake the river crosses into Lincoln county, winds back and forth across the Creek–Okfuskee county lines, crosses Okmulgee County, and into Eufaula Lake near the Okmulgee–McIntosh county line. Communities along the waterway are Arcadia, Luther, Wellston, Warwick, Sparks, and Welty. It is impounded by Arcadia Reservoir and by Eufaula Lake. Near Okmulgee, the river meanders through the 9,600-acre (39 km2) Deep Fork National Wildlife Refuge.
The Deep Fork has a total length of 370 kilometres (230 mi) and has a long narrow drainage basin averaging 40 kilometres (25 mi) in width. The Deep Fork flows through a region of red sandstone hills and red soils and the river is of the same color. The river is channelized in its upper course. The Deep Fork runs in a narrow channel, about 100 ft (30 m) wide at normal flow, frequently obstructed by fallen trees, and often enclosed by steep red clay banks as high as 100 ft (30 m). The river is prone to flooding, especially in its lower course where it is bordered by an extensive area of wetlands, temporary and oxbow lakes, and a deciduous bottom land forest, some of which is included in the Deep Fork NWR. The upper courses of the river are usually bordered by a narrow band of forest.
