I got a job to build a deck on a lake front house, kerr lake – va. I was planing to use treated lumber from lowes, either standard acq or severweather, depending on customers request / buget.
Someone just told me that I need to use a special “salt treated” lumber for anything in close proximity to water, in this case about 150 feet from the lake.
Is this correct, and if so where do I find such lumber around here… raleigh, nc.

I live in the Raleigh area too... I think the term "salt treated" is more of a good old boy slang term than an actual factual kind of thing. I think what you are talking about is .60 or .80 treated lumber. I know it is commonly available closer to the coast, but not sure about here in Raleigh. Check with Brooks Lumber, Tarheel Wood Treating and Stock Building Supply. If they don't have it I'm sure they can get it. Or, you may want to just do the posts from the stuff with the .60 saturation rate. Really though, this is more of a concern in salt water environments than fresh water, especially 150' from the water, assuming that the location will not be regularly flooded.
BTW- for any of you Yankees, and I think we have a few :-) Kerr lake is pronounced "car" ... no - not that "car" with the short a... :-)
Unless it is IN the water no use std PT lumber.
In fact I am working on the design of one that will be about 12" above the water, AKA a floating dock, and it will use std PT lumber.
