Water Quality Assessment
Stream monitoring stations from the USGS National Water Information System (NWIS) and EPA’s STOrage and RETrieval and Water Quality eXchange (STORET-WQX) databases are available for selection and analysis. Our tools can also be used to download stream flow (daily average or 15-minute), water quality, and annual peak discharge data.
Users can view results and model outputs in a variety of options including:
- Time series graphs
- Envelope plots
- Cumulative distribution function (CDF) graphs
- Flood and drought magnitude-frequency plots
- Duration curves
