StreamStats is a digital, map-based tool designed to provide information about streamflow and the upstream watershed of any selected point on a stream. The tool can assist in water resources planning and management and support engineering and design projects. In Montana, the primary capabilities of the application include basin delineations, basin-characteristic measurements, estimates of streamflow characteristics, and regional regression equations.
What can StreamStats do in Montana?
StreamStats allows users to find streamflow and watershed information by selecting any point on a stream in Montana. The application then reports calculations (such as the contributing drainage area upstream of that point), provides relevant watershed characteristics, and flow statistics where data are available.
In addition to using the StreamStats tools in the application, users can also visit the Montana Regional StreamStats Information Portal. This portal displays the data and information that are available for download and drainage calculation.
New - Identifying upstream dam regulation
Montana StreamStats now includes an option that allows a user to check for upstream regulation. This tool identifies areas within a chosen watershed that are regulated by dams. If dams exist within the watershed, the tool calculates the drainage area both upstream and downstream of those dams, pinpoints the regulated areas on a map, and determines the percentage of the watershed that is regulated. When a basin characteristics report is generated, the table will display values for the entire watershed as well as for the regulated portion.
To use this feature, follow the steps below:
- Delineate the watershed for a selected point
- Then select "Check for Upstream Regulation" button
- The application then maps the watershed for all dams upstream of the selected point and calculates the percentage of the total watershed area that is regulated.
- Select "Download Basin" button. The main watershed and the regulated watersheds can then be downloaded to GeoJSON, Shapefile, or KML format of user’s choice.
Creating Montana StreamStats
Montana StreamStats was developed in partnership with the Montana Departments of Environmental Quality, Montana Department of Natural Resources and Conservation, and Montana Department of Transportation. A USGS Scientific Investigations Report details this project in seven interconnected chapters. Chapter A introduces the Montana StreamStats application, the basin and streamflow datasets, and summarizes the streamflow characteristics and regression equations used in the study. Chapters B through E document the data, methods, and results used to determine streamflow characteristics (e.g., peak-flow frequencies, low-flow frequencies, and monthly/annual characteristics) for USGS streamflow-gaging stations in and near Montana. Chapters F and G describe the StreamStats analytical tools, which allow users to delineate drainage basins and apply regression equations to estimate streamflow characteristics at ungaged sites in Montana.
