FALLS CREEK (Garza County). Falls Creek rises a mile northeast of Pleasant Valley in northwestern Garza County (at 33°15' N, 101°27' W) and runs east for eight miles to its mouth on the North Fork of the Double Mountain Fork of the Brazos River (at 33°16' N, 101°22' W). The stream passes through moderately steep slopes with high local relief, surfaced by shallow to moderately deep silt loams that support mesquite and grasses.
