Middleton WI 53562 USA (608) 821-3871 lhubbard@usgs.gov USEPA No formal attribute accuracy tests were conducted No formal logical accuracy tests were conducted Data set is considered complete for the information presented, as described in the abstract. Users are advised to read the rest of the metadata record for additional details. No formal positional accuracy tests were conducted No formal positional accuracy tests were conducted Used the R package 'dataRetrieval' to pull the data from NWIS web. We developed several steps to pre-process the data in R before using rloadest to develop regressions for site and constituent. 2016 Processes are fully described in the associated journal paper. 2016 both This paper describes the USGS tributary monitoring program and how it is computing loads using surrogate regression.
