It appears that the new dredged opening
to Vinson Slough is nearly closed. It is unlikely to remain open
long since Vinson Slough connects with Aransas Bay only at very high
tides.
Here are some more photos
of
the salt near Cedar Bayou. I saw no salt further south on San
Jose Island or on Mustang Island. There is a pretty large
salt
pond just inland of Mission Bay in the Mission River delta.
Tony
Amos just informed me that he measured the salinity in one of the few
remaining ponds in Vinson Slough near the Gulf. It was 76ppt.
The following commentary is by Dick Hoese, a marine biologist
who
has been studying this area just about forever.
Not sure about San
Jose. In summer, 1955, what is now Harbor Oaks Harbor in Rockport was a
salt pan. There were small ones on Harbor Island the summer of 1964. Do
not remember any in 1970, but there were some around
Baffin, and Celia stopped things. My neighbor on the
Johnson
Ranch in Lamar found the old salt works on St. Charles Bay and there
has been some archeological work there. Since the flats stop somewhere
around here I have wondered what the northern limit was because the
LaSalle expedition in 1685 reported them. A corrpespondent
sent
me a historical record of settlers drying salt somewhere
around
Matagorda Bay, but have not checked it out. We have only had this
property for a little over a decade, but what seems unusual is the hot
weather from the high pressure during the time of maximum sun azimuth
with little clouds. It feels like Mexico.
Evaporation rates
seem unusual, but have not seen any data.
I started my thesis on Cedar
Bayou in 1956 and do not remember any. There were also some aerials
taken around then, but do not recall seeing any salt. Will
ask
the old timers.
We have had unprecented
wet weather since then, at least in modern Texas history, so while I
hope it rains it will be interesting if we return to an earlier
pattern
