Fish in Spring Creek….don’t eat! (August, 2009 update)

The USGS recently released a report stating that all stream fish in the US are contaminated with mercury  (methyl mercury), mostly due to atmospheric pollution from concrete plants (Texas has Plenty of those),  coal-fired power plants, and trash burning.  The highest concentrations of methyl mercury were found in largemouth, smallmouth, and spotted bass, so fishermen beware.  Is anyone going to clean up the mercury? Nope,  not an option.

Texas has fish consumption advisories in place for certain species. A full list of such warnings is available athttp://www.epa.gov/waterscience/fish/advisories.

 

Excerpts from field sampling and reconnaissance of Big Spring Creek environments:

 

A major feature of the riparian forest is Big Spring Creek.  The creek is fed by numerous springs and seeps from the Austin Chalk bed through which it cuts its course.  Benthic organisms were not observed to be very abundant in the creek, a probable result of flushing and bottom scour by floods.  Benthic primary production was represented mostly by diatoms.  In addition, there was some growth of filamentous algae (Cladophera glomerata and Campsopogon sp.) observed in the creek, but not enough to indicate eutrophic conditions. Macrophytes such as Anacharis (Elodea) and Chara were of very limited distribution in the creek.
