Summary

This metadata record describes 7 conservation practice based on information from the National Resource Conservation Service (NASS) (Michael Schwartz, USGS, written communic. 2017). These data are for the year, 2012 and compiled for two spatial components of the NHDPlus version 2.1 data suite (NHDPlusv2) for the conterminous United States; 1) individual reach catchments and 2) reach catchments accumulated upstream through the river network. The 7 conservation practices for included are : Land artificially drained by ditches, land drained by subsurface tiles, land on which conservation tillage was used, land on which conventional tillage was used, land on which no-till practices were used, land planted to a cover crop (excluding conservation [...]

Purpose

This data set was created by the U.S. Geological Survey's (USGS) Hydrologic Systems Team which is part of the USGS National Water Quality Program (NWQP). This effort was undertaken to estimate the 7 conservation practices for NHDPlusV2 flowline catchments and upstream river networks to support statistical analysis, map display, and model parameterization.
