Summary

This tabular data set represents estimated mean annual snow as a percent of total precipitation, 1905-2002 compiled for two spatial components of the NHDPlus version 2 data suite (NHDPlusv2) for the conterminous United States; 1) individual reach catchments and 2) reach catchments accumulated upstream through the river network. This dataset can be linked to the NHDPlus version 2 data suite by the unique identifier COMID. The source data for estimated mean annual snow as a percent of total precipitation was produced by the USGS (Wolock, written communic., 2012) and processed based on the methods described by McCabe and Wolock (USGS, 2009). Units are percent. Reach catchment information characterizes data at the local scale. Reach catchments [...]

Purpose

This data set was created by the U.S. Geological Survey's (USGS) National Water-Quality Assessment Project (NAWQA) which is part of the USGS National Water Quality Program (NWQP). This effort was undertaken to estimate the mean annual snow as a percent of total precipitation, 1905-2002 for NHDPlusV2 flowline catchments and upstream river networks to support statistical analysis, map display, and model parameterization.
