In the most recent years, the clarity of the water near the shoreline has “gotten considerably worse,” said John Reuter, the center’s associate director. Besides crayfish, other newer invasive species found in shallower waters, including Asian clams and Eurasian watermilfoil, an aquatic weed, are causing the clarity to deteriorate.
The League to Save Lake Tahoe, a 55-year-old private organization that engages in conservation activities, including sending volunteers to uproot Eurasian watermilfoil, said the new rules guiding crayfish harvesting are strict enough to protect the lake’s environment and recreational use.
