Data collected to assess water quality conditions in the natural creeks, aquifers and lakes in the Austin area. This is raw data, provided directly from our Water Resources Monitoring database (WRM) and should be considered provisional. Data may or may not have been reviewed by project staff. A map of site locations can be found by searching for LOCATION.WRM_SAMPLE_SITES; you may then use those WRM_SITE_IDs to filter in this dataset using the field SAMPLE_SITE_NO.

The Environmental Integrity Index (EII) is a tool developed by the City of Austin’s Environmental Resource Management Division to monitor and assess the ecological integrity and the degree of impairment in Austin’s watersheds. This feature class provides the most recent results from the EII for the City of Austin Watershed Protection Department’s Masterplanning process. Similarly, the Austin Lakes Index was designed to provide a yearly assessment of the ecological integrity of Lake Austin, Lady Bird Lake, and Lake Long.

Index scores (from both the EII and ALI) are an integer between 0 and 100. Excellent 88-100 | Very Good 76-87 | Good 63-75 | Fair 51-62 | Marginal38-50 | Poor 26-37 | Bad 13-25 | Very Bad 0-12.

Problem Scores are an integer between 1 and 100 with 1 being "No Problem" and 100 being a highest priority.
