Hydro Flow Metrics Historical (Map Service)

This map service represents modeled streamflow metrics from the historical time period (1977-2006) in the United States. In addition to standard NHD attributes, the streamflow datasets include metrics on mean daily flow (annual and seasonal), flood levels associated with 1.5-year, 10-year, and 25-year floods; annual and decadal minimum weekly flows and date of minimum weekly flow, center of flow mass date; baseflow index, and average number of winter floods.�These files and additional information are available on the project� website,�<a href="https://www.fs.usda.gov/rm/boise/AWAE/projects/modeled_stream_flow_metrics.shtml" rel="nofollow ugc noopener noreferrer" target="_blank">https://www.fs.usda.gov/rm/boise/AWAE/projects/modeled_stream_flow_metrics.shtml</a>. Streams without flow metrics (null values) were removed from this dataset to improve display speed; to see all stream lines, use an NHD flowline dataset.<div><br></div><div>Hydro flow metrics data can be downloaded from�<a href="https://data.fs.usda.gov/geodata/edw/datasets.php?xmlKeyword=hydro+flow+metrics" rel="nofollow ugc noopener noreferrer" target="_blank">here</a>.<br></div><div><br>This record was taken from the USDA Enterprise Data Inventory that feeds into the <a href="https://data.gov">https://data.gov</a> catalog.
