Index Value Plot

This index value plot represents the streamflow for Florida over the last 45 days. This particular index value 

plot represents daily values; there is no limit to the values that could be used. I wanted to compare FL to GA 

mainly due to the drought conditions in Georgia that are affecting the Apalachicola River area.
