![]() Streamflow records provide information for a range of people including emergency responders, water managers, environmental and transportation agencies, researchers, utility companies, and consulting firms 1, 2, 3. Laslty, we describe an R package that expedites data retrieval with examples for multiple use-cases. These datasets have been made accessible via an OPeNDAP enabled THREDDS data server for public use and a brief analysis highlights the latest version of the model should not be assumed best for all locations. In this work we describe a reproducable process for restructuring a sequential set of NWM steamflow files for efficient time series access and provide restructured datasets for versions 1.2 (1993–2018), 2.0 (1993–2020), and 2.1 (1979–2022). In the most recent release, extracting a complete streamflow time series for a single location requires managing 367,920 files (~16.2 TB). ![]() In all released to date, the files containing simulated streamflow contain a snapshot of model conditions across the entire domain for a single timestep which makes accessing time series a technical and resource-intensive challenge. With many versions, an hourly, multi-decadal historic simulation is made available to the public. ![]() In 2016, the National Oceanic and Atmospheric Administration deployed the first iteration of an operational National Water Model (NWM) to forecast the water cycle in the continental United States. ![]()
