ONION CREEK (ELLIS COUNTY)
ONION CREEK (Ellis County). Onion Creek is formed by the confluence of Big Onion and Little Onion creeks five miles northeast of Avalon in south central Ellis County (at 32°14' N, 96°45' W). The stream runs east for 9½ miles to its mouth on Chambers Creek, within one mile of the Navarro county line (at 32°13' N, 96°36' W). Trinity clay composes the soil along the entire length of the watercourse. This fertile alluvial soil, which has a depth of ten inches and varies from a brownish-black to black clay, produces excellent yields of cotton, corn, and alfalfa. In the late 1940s a small farming community called Onion Creek was located on this stream near the Navarro county line.
