Not if you only open when the intracoastal is higher than the marsh. Or have a large check valve type system where it can only flow one way.

Oh, and there would be no tides when the wiers on the lake are closed anyways. That's when you would let the water in from the other side.

Salinity high = open wier on intracoastal side.

Salinity low = open wier on the lake side.
