Above Station <br />No. 612 they were designated arbitrarily by this office. <br /> <br />Discbarae: Average annual or monthly discharge of the station in <br />cubic feet per second. <br /> <br />Number of Davs: Number of days in tbe month or year during whicb <br />discharge and quality data were available. <br /> <br />Webhted Averalte - ppm: The annual or monthly average concentration <br />in parts per million of the mineral constituent concerned <br />adjusted to corresponding discharge. Blank space in this <br />column indicates data not available. <br /> <br />WeiRbted Averalte - T/D: The annual or monthly average quantity of <br />tbe appropriate mineral constituent in tona per day adjusted <br />to corresponding discharge, Blank space in this column <br />indicates either data not available or tonnag~ less tban 0.5 <br />tons/day. <br /> <br />Max. - ppm: The maximum concentration in parts per million of the <br />appropriate mineral constituent whicb was recorded as the <br />result of tbe analysis of one composit semple during tbe <br />month or year. Blank space in this colUllDl indicates data <br />not available. <br /> <br />Min. - ppm: The minimum concentrstion in parts per million of the <br />appropriate mineral constituent which was recorded as tbe <br />result of the analysis of one compos it semple during the <br />month or year. Blank space in this column indicates data <br />not available. <br /> <br />WeiRbted Data Av~.: The annual aversge concentration or quantities <br />of the various mineral constituents adjusted to discharge, <br />the maximum and minimum values of these constituents, the <br />average discharge, and the total number of days for all data <br />avsilable during s particular water year. These figures may <br />not represent the entire water year. <br /> <br />Water Year: A period of time lasting twelve months beginning <br />October 1 of One year and ending September 30 of tbe year <br />designated as tbe wster year.
