When attempting to run tutorial02.py in the flopy/examples/Tutorials/Tutorial02 subdirectory, I had an error issued based on the following argument from line 153:
plt.clabel(cs, inline=1, fontsize=10, fmt='%1.1f', zorder=11)

The error reads as follows:
TypeError: clabel() got an unexpected keyword argument 'zorder'

I believe the zorder argument should be removed from this command. Once I did so, the rest of the file ran fine. However, if there's a better way to solve this problem, I'd welcome it.
Thanks!
