Environmental Integrity Index (EII) Phase I & II data collected during 2009 and 2010 are presented and evaluated within the context of historical EII data. Forty-nine watersheds throughout the greater Austin area were sampled 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 other programs. The values are also used in the WPD 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 graph that shows how Waller Creek's EII compares against nearby Austin creeks.
