the real tragedy for these fish will be when we run out of Nueces (already for more than a decade), Guadalupe and (eastern) Colorado river discharge because of population growth and groundwater use, and turn our mangrove estuaries into this:
The mouth of the western Colorado river at the Sea of Cortez was once the largest mangrove estuary on earth. The same people from southern California who did this in our lifetime are now moving their equities to Texas. They have the right to do so, but we also had the need 20 years ago to begin desalination for public water supply. The first permit was approved by TCEQ after scientific advisory board review, but is also now held up in court by CCA and Sierra Club. (same thing Sierra Club did in California to block their desalination)

Jim, I've been on this soapbox for 20 years.
And unlike the freeze-kill, this is something that is Within Our Control
If you guys want to Survey something and post it on the internet, drive by Labonte Park every day, take video of the dry weirs on the Nuecces river discharge, and remind the state that Corpus Christi's only source for municipal water supply is draining this river dry from Lake Corpus Christi, and that Corpus is contracted to continue this way until 2040; also, that since 2003, Nueces River discharge has been below the minimum required for health of the bay system established in EPA 1994.
We have increased fertilizer run-off combined with decreased river discharge. We have phosphorus fall fertilizers which are never needed in Texas, choking our rivers with hair algae. When the rivers stop delivering calcium to the bays, the mollusks and crustaceans will disappear. If you want to document something, document the brown tides that appear in Upper Lagune Madre every summer.
