This file (wymt_ffa_2018D_WATSTORE.txt) contains peak flow data for peak-flow frequency analyses for selected streamgages in and near the Milk River Basin, Montana, based on data through water year 2018. The file is in a text format called WATSTORE (National Water Data Storage and Retrieval System) available from NWISWeb (http://nwis.waterdata.usgs.gov/usa/nwis/peak).
This file is used as input to the U.S. Geological Survey PeakFQ computer program used for peak-flow frequency analyses.

In some cases, peak flows obtained from NWIS were modified using one of the three methods described in Sando and McCarthy, 2018, Sections "Pre-Analysis Data Combination", "Pre-Analysis Data Correction", and "Procedures for Modified Maintenance of Variance Extension Type III record Extension". USGS streamgage identification number (columns 2 - 9) is appended with analysis designation in the format XXXXXXXX.AB where XXXXXXXX is the streamgage identification number, A is the regulation status for the analysis period, and B is the type of peak-flow frequency analysis. Values of A (regulation status) are defined as: A = 0, unregulated; A = 1, regulated by major regulation; and A =2, total; that is, the combined unregulated and regulated peak-flow records for streamgages with peak-flow records before and after the start of regulation. Values of B (type of peak-flow frequency analysis) are defined as: B = 0, at-site peak-flow frequency analysis conducted on recorded data; B = 1, peak-flow frequency analysis conducted on combined recorded and synthesized data; synthesized data from Maintenance of Variance Extension Type III (MOVE.3) record extension procedure; B =2, peak-flow frequency analysis determined from regional regression equations (RREs); and B = 3, at-site peak-flow frequency analysis weighted with results from RREs.
