Figure 7. Water temperatures measured at bottom probes (situated at the bottom of the water on top of the substrate) at three hydrostations in Everglades National Park during the record cold spell in January 2010. L31W is a canal site, P37 is a marsh site on the western edge of Taylor Slough, and TSB is similar to an alligator hole (deeper than marsh) not far from the L31W Canal. Note that lethal temperature limits for most common nonnative fish species found in the Everglades are all below 15°C; only in the canal site did temperatures remain above this threshold.
