Agreed Smalls. The entire marsh behind the weirs was the saltiest on record to say the least. Since the end of the drought there's been a huge improvement in the overall health of the marsh. Thankfully we have the weirs to thank by retaining some of this freshwater and guide it to the brackish/fresh marsh it was. If you're ever curious on the marsh salinity behind the weirs you can view near real time readings on this site. You click on the small icon that is in marsh behind the weirs and you can see for yourself.
