Data Quality Information:
Horizontal Positional Accuracy Report: Good - lakes added by digitizing as needed

Source information:
Source scale denominator: 0
Type of source media: None
Source contribution: 100K nhd, various 24k products and multiscale digitizing

Process step:
Four new fields (OUTFLOW_TO, OUTFLOW_TO_N, OUTFLOW_TO_M, FWB_ID) were added to help maintain consistency with the Fisheries Information System tables.
Process step:
Lakes were created by first taking all the 1:100,000 scale lake layers available from the USFS and BIA. The 1:24,000 scale NHD lakes were used to fill in the gaps and other missing lakes were digitized. Lake names were updated using the USGS GNIS names and other sources. Lakes are digitized as needed from the 1:24,000 scale USGS topographic, DOQQ digital maps and National Wetlands Inventory.
