1. I need to add the Wellsville gauge on the Arkansas river and don't know how.

It is the winter gauge for most of the Ark downstream of Salida.

2. Is it possible to add two gauges to a single section. See above question.

It is possible to add two gauges to a single section. However, I do not see any Colorado DWR gauges in the AW gauge database yet. That means a method for grabbing those gauges has not been written yet. Keep pestering till it gets done.

In the meantime, include links to that gauge on the appropriate rivers. You may also be able to embed the graph from that gauge into the AW page. Try copying the graph and pasting it into the AW page. Then see if it updates correctly.

The only issue with embedding the graph directly into the river description is that the graphic might be cached on the browser side and not show up correctly or show up as an old version. If you're willing to live with that possibility than embedding the graph works great.
