POWDER CREEK. Powder Creek rises (at 33°34' N, 96°05' W) in the southwestern central portion of Fannin County. Its flow is intermittent in its upper reaches, where it passes through slightly acidic clay loams. The land around the creek is rolling prairie and was once covered in native grasses and scattered stands of oak trees. The creek also was formerly lined with bois d'arc, sycamore, cottonwood, and hackberry trees; where the creek passes around Bonham the trees have been preserved. Powder Creek does not flood frequently as it moves from northwest to east, but the Texas and Pacific Railway constructed two small pools in Bonham near the mouth of the creek, which has been channeled slightly to the north from its old mouth to join Bois D'arc Creek (at 33°34' N, 96°09' W). At one time the creek may have served as the southern boundary of the Willow Wild Cemetery.
