I noticed that WA DOE made changes to their webpages that actually now make it possible to download all of the flow data for current and past years at 15 minute data intervals. They have a new tabbed interface. So, for example, go to the CC Stilly page and choose the Flow tab. Scroll way down and there is a link to 15-minute data table (just above the historical data). Choose that and you get the current water year in 15 minute intervals. So, for example, at 8:30 this morning CC Stilly was at 415. There is obviously an error component to the measurement but it is more precise than the graph - especially with the automatic scaling done to their graphs.

Yay!!!!!!!!!!!!!
