Environmental Integrity Index (EII) Phase I & II data collected during 2013 and 2014 are presented and evaluated within the context of historical EII data. 118 sites located within 50 watersheds throughout the greater Austin area were sampled to assess environmental conditions. This data is primarily used for prioritizing subwatersheds for Capital Improvement Projects, regulations and/or other programs through the Citywide Watershed Protection Department masterplan. The values are also used in the WPD Business Plan as performance measures for water quality maintenance. The baseline information accumulated through the EII provides a large, comprehensive and quality assured dataset unique to our region which can be utilized for identifying and tracking both anthropogenic and climatic changes to our aquatic resources.
