This dataset was created for two main purposes; (1) summarize and provide refined spatial detail to attributes of agricultural practices from the 1992 NRI dataset; and (2) to support hydrologic modeling. The U. S. Geological Survey's (USGS) National Water-Quality Assessment (NAWQA) program is using the spatially refined LWWIS dataset to produce ancillary information for characterizing surface and ground-water sampling sites. Calculation of percentages of NAWQA study areas treated by Stream, Lagoon or Other Waste Waster (not including tailwater recovery) as an Irrigation Source is one example of the type of use of this data set. The 1992 NRI data was used because it was created in the same early to mid-1990s time frame as the NLCD. NAWQA plans on processing the NRI in this fashion every 5 years as new NRI and NLCDE data are published.
