In this assignment, you will calculate and interpret wetland hydrographs. Consider the data provided below and answer the following questions.
1. Given the following measurements of an inland wetland’s water levels, create a hydrograph. Be sure to label all axes.
Note: there are multiple years of data. You can either plot all the data on one line, with multiple years on the x axis. Or, you may plot separate, overlapping lines (in which case label the years).
Note: You can create your hydrograph in Excel (recommended) or any other software program. Or, you may neatly draw the hydrograph and upload a scan of your work.

2. Describe your hydrograph in text. Include descriptions of the wetland's depth, frequency, duration, and seasonal pattern of flooding. Assuming the growing season is April through September, what is the wetland's water regime?
