FILE UPDATED:~ June 14, 2018 with new 10-year (2008-2017) and long-term (1985-2017) trend in flow normalized loads for the 9 River Input Monitoring (RIM) stations for the period 1985-2017.~~~~ RIM STATIONS INCLUDE:~ STATIONS: 01491000, CHOPTANK RIVER NEAR GREENSBORO, MD.; 01578310, SUSQUEHANNA RIVER AT CONOWINGO, MD; 01594440, PATUXENT RIVER NEAR BOWIE, MD.; 01646580, POTOMAC RIVER AT CHAIN BRIDGE, AT WASHINGTON, D.C.; 01668000, RAPPAHANNOCK RIVER NEAR FREDEROCKSBURG, VA.; 01673000, PAMUNKEY RIVER NEAR HANOVER, VA.; 01674500, MATTAPONI RIVER NEAR BEULAHVILLE, VA.; 02035000, JAMES RIVER AT CARTERSVILLE, VA.; 02041650, APPOMATTOX RIVER AT MATOACA, VA.~~~ TERMS:~ Station ID, USGS Station ID; Station Name, Station name; P Code, Parameter code; P00600, Total nitrogen (as N); P00631, Nitrate (as N); P00665, Total phosphorus (as P); P00671, Orthophosphorus (as P); P80154, Suspended sediment; Start Year, First water year of modeling period used to estimate load.; End Year, Last water year of modeling period used to estimate load; Trend Period, Length of period over which trend is computed, in years, through 2016.; Lower Confidence Interval, Change in Load = Lower confidence limit (90%) of the estimated change in load, in 10^6 kilograms per year (kg/yr).; Estimated Change in Load, Estimate of flow-normalized load change in Trend Period, in 10^6 kilograms per year (kg/yr).; Upper Confidence Interval, Change in Load = Upper confidence limit (90%) of the estimated change in load, in 10^6 kilograms per year (kg/yr).; Change in Load in Percent, Total change in flow-normalized load in percent.; Direction of Change in Load, Trend direction, with 3 categories: No Trend, Degrading, Improving.; Likelihood that Load is Changing, Likelihood of trend direction, with 4 categories: as Likely as Not (likelihood coef, >0.33 and <0.67), Likely (likelihood coef, >=0.67 and <0.90), Very Likely (likelihood coefficient, >=0.90 and <0.95), Extremely Likely (likelihood coefficient, >=0.95 and <=1.0).~~~~ METHODS:~ Nutrient and suspended-sediment concentrations and loads and flow-normalized concentrations and loads were estimated using a weighted regression approach called Weighted Regressions on Time, Discharge, and Season (WRTDS) (Hirsch and others, 2010), which is included in the R (version 3.4.0) software package called EGRET - Exploration and Graphics for RivEr Trends (version 2.6.0) (Hirsch and DeCicco, 2015). The uncertainty associated with the trends of nutrient and sediment loads was estimated using the R package called EGRETci (version 1.0.2) The application of WRTDS to generate the results provided in this table is documented in Chanat and others, 2016.
