Clear Lake Habitat
A freshwater marsh once surrounded Bloody Island prior to land reclamation efforts that began in the late 19th century. Native plants within marshes around Clear Lake included tules (Scirpus acutus), rushes (Juncus sp.), sedges (Carex sp.), and cattails (Typha latifolia). Associated tree species consisted of cottonwood (Populus fremontii), willow (Salix sp.), and elderberry (Sambucus sp.). A dense expanse of tules and willows once stretched all the way from here to the city of Lakeport. The marshes flooded in the winter and spring but became dry in the summer months. This seasonal cycle and the ecosystem it supported were disrupted when land speculators and ranchers drained marshes to create agricultural fields.
The following fish species were native to Clear Lake:
Rainbow trout (Oncorhynchus mykiss)
Thicktail chub (Gila crassicauda)
Clear Lake splittail (Pogonichthys ciscoides)
Sacramento pikeminnow (Ptychocheilus grandis)
Sacramento sucker (Catostomus occidantalis)
Sacramento perch (Archoplites interruptus)
Clear Lake Hitch (Lavinia exilicauda chi)
Tule perch (Hysterocarpus traskii)
Prickly sculpin (Cottus asper)
Of these native species, only the blackfish, hitch, perch, and prickly sculpin are still common in Clear Lake. All other fish that are common in the lake today- including bass, carp, catfish, crappie and bluegill-are non-native, introduced species.
