Blackwater Draw is an intermittent stream channel about 140 km (87 mi) long, with headwaters in Roosevelt County, New Mexico, about 18 km (11 mi) southwest of Clovis, New Mexico, and flows southeastward across the Llano Estacado toward the city of Lubbock, Texas, where it joins Yellow House Draw to form Yellow House Canyon at the head of the North Fork Double Mountain Fork Brazos River.
