Keya Paha River

River in Nebraska, United States

The Keya Paha River (/ˈkɪpəhɔː/ KIP-ə-haw)[4] is a river flowing 127 miles (204 km)[5] through the U.S. states of South Dakota and Nebraska.

Quick Facts Location, Country ...

The name is derived from the Dakota language ke'-ya pa-ha', meaning "turtle hill",[6] specifically Turtle Butte.[7] The river's name was given to Keya Paha County, Nebraska, through which it flows.[8]

The river originates in Todd County in south central South Dakota, at the confluence of Antelope Creek and Rock Creek near the town of Hidden Timber.[9] It flows in a generally southeasterly direction through Todd and Tripp counties in South Dakota and then through Keya Paha and Boyd counties in Nebraska.[1] It ends at its confluence with the Niobrara River about 7 miles (11 km) west of Butte, Nebraska.[10] The river has a year-round flow, except for winter ice, and has a quality of water better than all other South Dakota rivers.[11]

In 1861, the border between the Nebraska and Dakota territories followed the Keya Paha River from the 43rd parallel to the river's confluence with the Niobrara; it then followed the Niobrara to Missouri. This situation lasted until 1882 when the boundary was changed to follow the 43rd parallel all the way to Missouri;[12] the change added portions of Keya Paha and Boyd counties to Nebraska.[13]

Discharge

At a gaging station south of Naper in Boyd County, the river's mean discharge was 138.6 cubic feet per second (3.92 m3/s). The maximum mean annual discharge was 389.4 cubic feet per second (11.03 m3/s), recorded in 1962; the minimum mean annual discharge was 44.5 cubic feet per second (1.26 m3/s), recorded in 1976.[14] The peak flow recorded at that point was 9,280 cubic feet per second (263 m3/s), registered on July 1, 1962.[15] From July 22 to July 30, 1976, the discharge was recorded as zero.[16]
