The Little Falls Gauge in the sidebar is now working correctly. It gives current height and flow data for the Little Falls Gauge, just above Washington on the Potomac. The raw data is available through the USGS. At first glance,a river gauge may not seem surf-related. On the other hand, it was this summer's abysmal east coast surf (and drought-level conditions on the rivers) that prompted me to keep better track of any paddling opportunities that might be out there. (Oh, yeah -- it was also a good experiment in parsing data with perl.)
