This watershed boundary consists of modeled lines and edited lines based on site plans and field investigations.

This data has been collected as part of a larger project by the City of Austin's Watershed Protection and Development Review Department to inventory its drainage infrastructure and create a GIS to store this information. The project includes an internal team developing a GIS based on record documents and an external team locating ground level appurtenances using GPS field collection units. The data in this data set represents the former.

Bar Ditch - A bar ditch is a man-made, open drainage-way into which excess surface water or groundwater drained from land, storm water runoff, or floodwaters flow either continuously or intermittently. It differs from a ditch in that it is typically less than 18 inches deep and contains driveway culverts of insignificant size (6" - 12"). A single line feature represents the entire line of ditch/culvert representing the bar ditch.This data has been collected as part of a larger project by the City of Austin's Watershed Protection and Development Review Department to inventory its drainage infrastructure and create a GIS to store this information.
