EZNEC's "fresh water" selection shows a conductivity of .001 (very unconductive). So it's talking about Great Lakes fresh water away from urban polution. Question would be how conductive the swamp water is. I would personally guess that if the area is heavily vegetated and slow draining, the conductivity would be higher due to dissolved compounds produced by submerged rotting vegetation.
Anybody care to go out in the middle of your local freshwater swamp and stick ohmmeter probes down there? The conductivity may even be layered, since the water with dissolved materials will weigh more and the more fresh will lay on top. If really stinky "fresh" water marsh is as conductive as that super-rich midwest pastoral soil we keep hearing about, it jumps up to the best of non-salt-water results. How conductive is YOUR local fresh water swamp. 73, Guy PS, this also applies to fairly acidic recently wet down pine straw forest floors, like those down in flat land Carolina loblolly or oak forests. Would vary incredibly depending on whether dry or not, or well drained with acid leached out.
