Attributes for NHDPlus Version 2.1 Catchments and Modified Routing of Upstream Watersheds for the Conterminous United States: Estimated 30-Year (1971-2000) Average Annual Runoff Based on Flow Measured at Streamgages, Millimeters per Year

This tabular data set represents estimated 30-year (1971-2000) average annual runoff in millimeters per year 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 was compiled by the United States Geological Survey (USGS, Dave Wolock written commun., 2012) based on based on flow measured at streamgages as described in Brakebill and others (2011). Units are millimeters per year. Reach catchment information characterizes data at the local...
