Description
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 ALI 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
– Marginal 38-50
– 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.

Data Fields
Name | Description | Type | Constraints |
---|---|---|---|
Watershed_ID | A Unique watershed Identification Number | integer | level : Nominal |
Watershed_Name | Official Watershed Name | string | - |
Integrity_Score_ID | Primary Integer Key for this dataset | integer | level : Nominal |
Watershed_Reach | 1 is most downstream reach and ascends for subsequent upstream reaches in the same watershed. | string | - |
Year_of_Observation | The City of Austin Fiscal year the data points are associated with. FY 2014 started on 01-OCT-2013 and ended 30-SEP-2014. | date | - |
Index_Phase | For streams only - one of two phases. Lakes all collected in same phase. | integer | level : Nominal |
Index_Source_Type | EII - Environmental Integrity Index or ALI - Austin Lakes Index | string | - |
Overall_Score | Overall Index Score. 100 = best condition. Average of other index scores. Problem scores not included. | integer | level : Interval |
Aquatic_Life | Aquatic Life Index score. 100 = best condition. (Bugs, diatoms abundance, diversity, pollution tolerance and other metrics) | integer | level : Interval |
Contact_Recreation | Contact Recreation Index score (for creeks only). 100 = best condition. (bacteria) | integer | level : Interval |
Eutrophication | Eutrophication Index score (for lakes only). 100 = best condition. In general, lower chlorophyll-a abundance and lower proportion of blue-green algae lead to a higher score to represent a superior trophic condition. | integer | level : Interval |
Habitat | Habitat Index score. 100 = best condition. Instream cover and substrate niches. | integer | level : Interval |
Non_Contact_Recreation | Non Contact Recreation Index score (creeks only). 100 = best condition. Aesthetics, odor, safety. | integer | level : Interval |
Sediment | Sediment Index score. 100 = best condition. Metals, pcbs, pesticides average. | integer | level : Interval |
Vegetation | Vegetation Index score (for lakes only). 100 = best condition | integer | level : Interval |
Water_Quality | Water Quality Index score. 100 = best condition. (nutrients, temp, tss) | integer | level : Interval |
Animal_Waste_Problem | Animal Problem score (creeks only). 100 = worst condition. Pet waste. | integer | level : Interval |
Construction_Runoff_Problem | Construction TSS Problem score (creeks only). 100 = worst condition. Erosion and Sedimentation controls failure. | integer | level : Interval |
Fertilizer_Problem | Fertilizer problem score (creeks only). 100 = worst condition. Nitrate. | integer | level : Interval |
Litter_Problem | Litter problem score (creeks only). 100 = worst condition. Trash | integer | level : Interval |
Riparian_Vegetation_Problem | Riparian Vegetation problem score (creeks only). 100 = worst condition. Not enough riparian cover. | integer | level : Interval |
Sediment_Problem | Sediment problem score (creeks only). 100 = worst condition. Worst of the problems set score. | integer | level : Interval |
Sewage_Problem | Sewage problem score (creeks only). 100 = worst condition. Water Quality problem caused by sewage. | integer | level : Interval |
Stability_Problem | Stability problem score (creeks only). 100 = worst condition. Stream bank failures. | integer | level : Interval |
Water_Quality_Problem | Water Quality problem score (creeks only). 100 = worst condition. Water quality worst case. | integer | level : Interval |
