Here is how to build a discharge graph using the USGS website:
1) open the site you're interested in
2) click on "Summary of all availbel data for this site"---this is just below the parameter box at the top of the page
3) select daily data from the available data
4) select "graph" as the output format and enter the Begin and End dates on the left. Note that the pop-up calander feature does not work (at least with explorer) you must enter the date range manually.
5) press go and enjoy
Thanks#1 Go to the site of the gauge you are interested in.
#2 Near the top there is a drop-down box that says "Available data for this site" and choose > "Time series: Monthly statistics"
#3 in the resulting page/Parameters box check the box next to "Cubic foot discharge"
#4 Enter the date range you want below that
#5 Below that just make sure the radio button for "Table of monthly mean" is checked
#7 The result is a text chart> Drag your cursor across JUST THE NUMBERS, YEARS AND MONTHS YOU WANT so they are highlighted in blue(I often leave out the years for a cleaner graph)
#8 While they are still hilighted hit ctrl and C at the same time (or right click and select> copy)
#9 Open excel and click in a cell. Hit ctrl and V at the same time (or right click and select> paste)
#10 Now in excel select all the months and cfs readings by dragging your cursor across them all
#11 Hit the "Insert tab" and you will see a little line graph that says "Line" under it. Hit that button, choose the style of graph you want
#12 Sit back and read your awesome chart and amaze your friends
