The Interagency Ecological Program’s (IEP) Environmental Monitoring Program (EMP) has historically monitored discrete water quality and nutrients in the San Francisco Estuary. The objectives of the EMP are to: (1) obtain consistent and accurate monthly data at established monitoring stations, (2) to provide and document information necessary to achieve compliance with salinity, flow, and dissolved oxygen standards, and (3) to report this information for the purpose of management and conservation of the upper San Francisco Estuary. This dataset is a subset of the larger EMP dataset that includes discrete water quality data collected from 2000-2018. Beginning in 2000, 11 stations were sampled for a full suite of water quality analytes while the remaining 11 were sampled for chlorophyll a and pheophytin a only, totaling 22 stations sampled each month. By 2018, that number increased to 28 stations sampled each month with the full suite of water quality analytes collected at every station. The EMP collects discrete water quality measurements 1-meter below the surface of the water and 1-meter above the bottom of the channel during high slack tide. Over the period of record, the following water quality parameters have been added: pH, total organic carbon, dissolved organic carbon, dissolved calcium, a rating score for the blue-green algae, Microcystis aeruginosa, and near bottom measurements.

Wastewater discharges are regulated by the Water Board. Those regulated are generally required to submit Self-Monitoring Reports to the State or Regional Water Board. Some dischargers submit their reports through the electronic Self-Monitoring Report (eSMR) module of the California Integrated Water Quality System (CIWQS). Generally these are for discharges into surface waters regulated by an individual National Pollutant Discharge Elimination System (NPDES) permit, though other dischargers may be included in this dataset as well. This dataset are the monitoring results that have been submitted as data points after the submitters have been approved for electronic submittals (i.e. after the "all electronic date"). Note that this dataset does not include records where the sampling date falls outside of the years shown below. The excluded records include: records where the sampling date is missing, records where the sampling date is invalid (e.g., records with sampling dates in the future or unreasonably far in the past), and records for samples taken prior to year 2006. The excluded records represent approximately 0.1% of all records in the complete eSMR dataset.

The Environmental Monitoring and Assessment Program (EMAP) National Coastal Database contains estuarine and coastal data that EMAP and Regional-EMAP have collected since 1990 from thousands of stations along the U.S. coasts. These data include water column data, sediment contaminants and toxicity data, and benthic macroinvertebrate and demersal fish community and contaminant data.

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.
