History
From 1970 to 1975, the USGS monitored the East Nodaway River about 6 miles northeast of Prescott; it was not monitored again until 2018 when it began to be monitored near Clarinda. In 1984, a fish kill occurred due to a pesticide spill, but the severity of the matter was unclear.Geography
East Nodaway River is the left tributary to the Nodaway River and joins it 4.3 miles before the Iowa-Missouri border. Most of the East Nodaway is located in Adams County, a short portion near its source is in Adair County, and the last third of the stream is located in Page and Taylor counties. The watershed of the East Nodaway extends also into Montgomery County and Union County.Communities
Corning is the largest city along the East Nodaway. Four other villages are located along the river: Brooks, Nodaway, Orient, and Prescott. Three other communities are located around the watershed but not along the river: Carl, New Market, and Quincy.Course
The East Nodaway River starts a mile west of Orient and flows south into Lake Orient. Afterwards, the river windingly flows southwest for about 15 miles before passing Prescott to the east. The river continues west-southwest and passes Corning to the south, then four miles later it does the same to Brooks, and after another 9 miles it passes Nodaway to the north and west. Then the East Nodaway River travels southwesterly until more than 20 miles before joining with the West Nodaway River to form the Nodaway River two miles southeast of Shambaugh.Hydrology
