Hello everyone – The attached ZIP file showsthe full year of stream level data for 2009. A few notes:

In order to make nine graphs big enough to be useful, I divided them into four groups. Group one is the rain gauge data, surface temperature and cave air temperature. Groups two, three and four are temp and depth from Thunder River, Carroll River and UL2 respectively.

All of the graphs use the same horizontal scale. If you print them all out and stack them vertically, they will line up.

The flat lines in the middle of the graphs for rainfall and surface temperature represent about 6 months when that data logger was out of service.

The graph for cave air temperature has several spikes in it. These are caused by handling the data logger when it is downloaded. They do not represent real cave temperatures.
