Weirs

Anyone else willing to offer a theory?

EVAPORATION ......

The marsh is like an enclosed lake, with just a very little in/out flow.

When the water keeps evaporating every day, the salt is left behind and the salinity keeps getting higher.

The water level in the Cameron Prairie [East Cove unit] has been about a foot lower that the average lake level for months now.
