PARTRIDGE CREEK. Partridge Creek rises in western Hamilton County (at 31°34' N, 98°18' W) and runs southeast for ten miles to its mouth (at 31°35' N, 98°08' W) on Cowhouse Creek. At the creek headwaters the terrain is flat with local deep and dense dissection and is surfaced by shallow, stony soil that supports oak, juniper, and some mesquite. As the stream progresses, the soil becomes more clayey, and grasses, chaparral, and cacti appear. Near the creek mouth, the terrain changes to steep slopes and benches, with shallow clay loams that support juniper, live oak, mesquite, and grasses. Parts of the area are used as rangeland.
