USFS - Modeled Historical Streamflow Metrics

This streamflow metrics feature class provides a high resolution, spatially explicit estimate of annual and summer flow volumes that can be used in more extensive studies of water quantity and water quality. Available water supply varies greatly across the United States depending on topography, climate, elevation and geology. Forested and mountainous locations, such as national forests, tend to receive more precipitation than adjacent non-forested or low-lying areas. However, contributions of national forest lands to regional streamflow volumes is largely unknown. This streamflow metrics feature class provides a high resolution, spatially explicit estimate of annual and summer flow volumes that can be used in more extensive studies of water quantity and water quality. In addition, the dataset highlights the relative importance of national forest lands to overall water quantity.
