Irrigation System by Tailwater Recovery on Agricultural Land in the Conterminous United States, 1992: National Resource Inventory Conservation Practice 447
This data set represents the estimated percentage of the 1-km grid cell that is covered by or subject to the
agricultural conservation practice (CP447), Irrigation System by Tailwater Recovery (ISTR) on agricultural
land by county. Irrigation System by Tailwater Recovery is described as "a planned irrigation system in
which all facilities utilized for the collection, storage, and transportation of irrigation tailwater for reuse have
been installed." (U.S. Department of Agriculture, 1995) Tailwater is the area immediately below a dam
where the river water is cooler than normal and rich in nutrients. This data set was created with geographic
information systems (GIS) and database management tools. The acres on which ISTR's are applied were
totaled at the county level in the tabular NRI database and then apportioned to a raster coverage of agricultural
land within the county based on the Enhanced National Land Cover Dataset (NLCDe) 1-kilometer resolution
land cover grids (Nakagaki, 2003). Federal land is not considered in this analysis because NRI does not
record information on those lands.
