Bull Creek Watershed Map

The Bull Creek watershed is framed by four highways: Research Boulevard, Loop 360, RR 620, and RM 2222. Much of booming Northwest Austin is drained by Bull Creek and its tributaries, but in the heart of the watershed-along Spicewood Springs Road, which cuts through the middle of the watershed-one finds horses, ranches, and seven low-water crossings. About 40% of the watershed is included in the Balcones Canyonlands Preserve, but compared to elsewhere in the foothills, there's not much actual parkland.
