Detailed Description

This close up shows the water in the western end of the lake. Greenish water zones tend to be hotter, and appear to be zones of groundwater influx into the lake. Submerged rocks are visible along the shoreline, and appear to have a brown or orange color. USGS photo by M. Patrick.
