This dataset can be linked to the NHDPlus version 2 data suite by the unique identifier COMID. The source data for 30 year average (1961-1990) of maximum monthly precipitation was originally PRISM-based data, with some further enhancements by ClimateSource.com and then provided to the USGS by the Environmental Protection Agency (Ryan Hill, EPA, written commun., 2011). Units are millimeters per month. It should also be noted that Climatesource.com no longer exists, however the data is free to distribute and the USGS assumes no liability with its use. It is included with this data set. Reach catchment information characterizes data at the local scale. Reach catchments accumulated upstream through the river network characterizes cumulative upstream conditions.  Network-accumulated values are computed using two methods, 1) divergence-routed and 2) total cumulative drainage area. Both approaches use a modified routing database to navigate the NHDPlus reach network to aggregate (accumulate) the metrics derived from the reach catchment scale.
