I am trying to create an isopleth map to illistrate the dilution of nutrients through a lake system.  Is it possible (how do I?), take into consideration the barriers (islands) in the lake.  Isopleth lines currently cross through the islands as opposed to following teh hydrologic flow around the islands?

Anyone encounter this issue, how can I resolve?
