Environmental Integrity Index (EII) Phase I data collected during 2006 are presented and reviewed. Sixteen of the 46 watersheds throughout the greater Austin area were analyzed to assess environmental conditions. These values are in use as part of the Citywide WPDRD masterplan in prioritizing subwatersheds to address through Capital Improvement Projects, regulations and/or programs. The values are also used in the WPDRD Business Plan as performance measures for water quality maintenance.


This report contains a massive amount of data regarding the contributing factors to the EII score. There is a summary sheet on the Waller Creek watershed that provides an overview of these scores from multiple locations in the creek. In addition, there are graphs showing how Waller Creek compares to nearby watersheds with a variety of water quality metrics.
