When reading any chart or graph, please keep in mind that space and software
limitations may create misleading spatial relationships. The Y-Axis may not
necessarily start at zero, further distorting spatial relationships among the
data. Furthermore, if multiple samples were taken on the same date at different
locations on the water body, multiple values are plotted for that date. This
presentation of the data explains the appearance of vertical lines on some of
the graphs. If you need to see accurate spatial relationships, we highly
recommend that you use the Data Download section, download the available data,
and graph according to your needs.
To download data, visit the
Data Download Tool in the Research section of the Lake Water Atlas.
