Re: ICW - what % fresh vs salt water

Yes, it's theoretically possible to get stratification.

But from a practical point of view, the estuary in question (it not really a river) has enough tidal current and is shallow enough that stratification is not going to happen.

The only time you might get close to fresh water (pretty much all naturally occurring water has some level of salt in it) would be after major rain events but it won't take long before the tidal events bring the salt levels back up to normal, so you can't really plan on it being fresh water.

If you are hopping fresh water will kill salt water growth on the bottom, don't count on it. Organisms have already figured out how to deal with varying salt levels.

If you want fresh water, you need to find an actual river and then go up far enough that tidal effects are overcome by the river's current.
