Dear all,

Is there a way to calculate from the DEM the total perimeter of all  
lakes (+reservoirs, etc.)? In other words, I need to calculate the  
total length of lake banks and so far could only determine the total  
lakes area, which is of no use in this case.

Thanks a lot for your help!

Sincerely yours,
