Lake Isabella, located in the southern Sierra Nevada Mountains, is a popular destination for fishing year-round. The lake provides a wide variety of fish species including trout, catfish, bass, and crappie. However, recently the lake has been closed to recreational fishing due to an outbreak of invasive Quagga mussels.
The Quagga mussel is a small mollusk native to the Caspian Sea which has been accidentally introduced into Lake Isabella and other California lakes. The mussels are highly invasive and can quickly dominate an environment if given the opportunity. They reproduce rapidly and can consume large amounts of plankton which are necessary for other aquatic species to survive.
The California Department of Fish and Wildlife (CDFW) has taken steps to prevent the spread of these invasive mussels by closing Lake Isabella to recreational fishing until further notice. This closure is an effort to prevent additional mussels from entering other bodies of water in California and beyond.
In addition to closing Lake Isabella for fishing, CDFW is also taking measures such as boat inspections and decontamination procedures at boat launch sites around the lake. These measures are intended to reduce the risk of spreading Quagga mussels from Lake Isabella into other waterways.
At this time, Lake Isabella is officially closed for recreational fishing due to an outbreak of invasive Quagga mussels. However, the California Department of Fish and Wildlife is taking steps to reduce the spread of these mussels by implementing boat inspections and decontamination procedures at boat launch sites around the lake. Hopefully these efforts will help protect other bodies of water in California from becoming infested with these destructive creatures.
