Geological Survey water-quality gaging <br />stations (approximately 214) having at least 25 dissolved <br />solids measurements; show USGS station number, station name, <br />starting and ending year of record, drainage area, total number <br />of observations having both dissolved solids and discharge, <br />effective period (years) of record, mean annual discharge, ~ean <br />flow-weighted dissolved solids concentration-- all based on <br />WATSTORE instantaneous QW measurements, rather than the daily <br />means computed by SLOAD. <br /> <br />B. List of 68 stations, grouped by major drainage basin, with <br />effective period of record exceeding five years. <br /> <br />...... <br />-..J <br />w <br /><D <br /> <br />C, Table showing computed streamflow and water-quality data for 68 <br />stations with an effective period of record exceeding 5 years. <br />Table will include annual and mean annual values for diSSOlVed <br />solids load and concentration, loads and concentrations of <br />major constituents, and streamflow. <br /> <br />D. List of .station records which were combined using adjacent <br />stations to increase the length of record-- showing station <br />numbers and names, and periOdS of record combined. <br /> <br />E. Monthly dissolved solids loads and concentration, monthly <br />concentration and mass fractions of constituents, and monthly <br />streamflow at the stations (20 to 30) selected for trend <br />analysis. <br /> <br />F. Regression statistics for dissolved solids and major <br />constituents at the trend analysis stations. <br /> <br />G. Long-term monthly averages of dissolved solids load and <br />concentration, concentration and mass fractions of major <br />constituents, and streamflow at the stations selected for trend <br />analysis. <br /> <br /> <br />H. Results of trend analysis including monthly and annual data for <br />dissolved solids load and concentration, and mass fractions-of <br />constituents. <br /> <br /> <br />I <br />j~ <br /> <br />" <br /> <br /> <br />15 <br />
