USGS StreamStats Application - A Review of the StreamStats Application and its Ecosystem of Services
The U.S. Geological Survey’s StreamStats program is a nationally supported, web‑based geospatial application that provides critical hydrologic information for engineers, planners, and natural resource practitioners. Through its map interface, users can obtain streamflow statistics, basin characteristics, and descriptive information for over 14,000 streamgages, or delineate a drainage basin at any location to generate estimates for ungaged sites. Built as an evolving Ecosystem of Services, StreamStats integrates high‑resolution geospatial datasets, regression and machine‑learning models, pre‑solved basin characteristics, hydraulic and hydrologic tools, and multiple specialized applications such as fire‑hydrology and time‑of‑travel analysis.
This presentation provided an overview of the StreamStats Ecosystem, demonstrating core functionality, emerging tools, and ongoing modernization efforts—including lidar‑derived hydrography, enhanced data processing capabilities, and expanded national services. We highlighted several new or recently deployed features that improve accuracy, flexibility, and discussed how StreamStats enables agencies to streamline workflows, reduce costs, and apply USGS hydrologic science in support of water‑resource decision making. https://www.usgs.gov/streamstats
