case_images: Careful evaluation of the dog's environment revealed access to several lakes with visible algal bloom (Figures 1 and 2).
case_images: Lake surface covered with a dense growth of Wolffia columbiana. W. columbiana is a small, free-floating aquatic plant commonly known as watermeal and native to California. Watermeal is non-toxic and thrives in nutrient-rich water, conditions suitable for cyanbacteria growth and toxin production.

case_images: Careful evaluation of the dog's environment revealed access to several lakes with visible algal bloom (Figures 1 and 2).
case_images: Lyngbya sp. identified in the lake water. Filamentous cyanobacteria with a thin, colorless sheath. Wet mount of lake water, x400 (scale bar = 20 mum).

case_images: Specific to cyanobacteria, the water sample contained Microchaete cf. uberrima, Lyngbya sp. (Figure 3), Pseudanabaena sp.,
case_images: Anabaena/Trichormus sp. identified in the lake water. Only one colony of filaments was observed in the sample. Akinetes, important characteristics morphological features were not present which prevented further identification to the lowest possible taxonomic level. Wet mount of lake water, x400 (scale bar = 20 mum).

case_images: Anabaena/Trichormus sp. (Figure 4), Microchaete sp., Scytonema sp., Calothrix sp., and Aphanothece elabens. Amongst the cyanobacteria identified, only Anabaena/Trichormus sp. and Lyngbya sp. were of toxicological significance.
