IRONS CREEK. Irons Creek, also known as Iron Creek and as Spring Branch, rises three miles northwest of Monaville in central Waller County (at 29°59' N, 96°03' W) and runs for eighteen miles, first south, and then curving southeast near Mount Zion, before reaching its mouth on the Brazos River, four miles west of Brookshire (at 29°47' N, 96°02' W). It travels primarily through loamy upland soils before entering an area of clayey soils near its mouth. The surrounding vegetation includes mesquite, prairie grass, and crops such as rice and cotton. The creek is reportedly named for John Irons, who received a tract of land in the area as one of Stephen F. Austin's Old Three Hundred in 1824.
