<p>I&rsquo;m interested in rivers (both ecologically and recreationally) and I want to know water level they are currently at, and how does that compare to their water levels throughout the year and in their recent history.

So I wrote these scripts that take a set of rivers and their associated gauge IDs, downloads the recent and historical data and generates a bunch of graphs.</p>
