Invasive golden mussels posing a threat to California's waterways.
The California Department of Water Resources is taking action against invasive golden mussels that threaten local ecosystems. First spotted in 2024, these small shellfish present a significant risk to California’s waterways by causing damage to fisheries and water delivery systems. Inspections of watercraft will begin at Lake Oroville next month, emphasizing the need for boaters to clean and dry their equipment to prevent the spread. Collaboration between state agencies and a $1 million funding boost aim to safeguard California’s precious water resources.
In an effort to protect the beautiful waterways of California, the Department of Water Resources (DWR) is gearing up to tackle a surprising and alarming invader—the golden mussel. First spotted in California waters back in October 2024, these little critters are causing quite a stir, and not in a good way!
Golden mussels are no ordinary shellfish. They are native to China and Southeast Asia and have recently found their way onto our shores, threatening to disrupt local ecosystems and economies. These mussels are small, measuring between three-quarters of an inch to two inches with a distinctive yellowish-brown shell. But don’t let their size fool you! Their rapid reproduction and ease of spread make them a formidable opponent when it comes to water quality and infrastructure.
Imagine your favorite lake or waterway turning murky or clogged up because of these little guys. They can easily attach themselves to hard surfaces, including boats and infrastructure. This could lead to serious issues like engine clogs, damage to fisheries, and even the fouling of water delivery systems. With potential impacts like these, it’s important for Californians to take action!
To keep our waterways safe, DWR is kicking off watercraft inspections at Lake Oroville and nearby State Water Project facilities starting next month. The goal? Prevent those pesky golden mussels from making their way to this critical reservoir. The inspections will help ensure that boaters are keeping their crafts clean and free of any unwanted hitchhikers.
Boaters are advised to take some simple steps to avoid spreading these invasive mussels. This includes cleaning and drying all equipment, draining water from devices, and removing aquatic plants and animal materials before and after using their boats. These precautionary measures are vital in keeping our beloved lakes and rivers free of mussels.
The California Department of Fish and Wildlife (CDFW) is also joining the fight against golden mussels, collaborating with DWR to enhance response efforts. A Golden Mussel Response Framework has been established, highlighting coordinated actions that both state and local agencies can take to minimize the spread and impact of these invasive species. This framework will provide much-needed strategies to mitigate ecological, water conveyance, recreational, and agricultural impacts caused by golden mussels.
CDFW has stepped up to provide $1 million in grant funding to assist boating facility operators in preventing mussel infestations. This financial support is essential in ensuring that facilities have the resources they need to stay mussel-free.
To further combat the spread, boats at Folsom Lake and Lake Clementine will undergo inspections and may be quarantined for up to 30 days. This precautionary measure is designed to minimize any potential risks of golden mussels spreading to those popular recreational spots.
With the U.S. Fish and Wildlife Service classifying golden mussels as a high risk for invasiveness in the continental United States, it’s crucial we act fast. These mussels can disrupt local ecosystems and economies, displacing native species and harming agricultural water systems. The goal of all these prevention measures is clear: avoid closing down our cherished water bodies while managing the threat that these invasive species present.
As beautiful as California’s waterways are, they need our protection now more than ever. The upcoming inspections and ongoing collaborative efforts between DWR and CDFW are a step in the right direction. Individuals must do their part by staying vigilant and following the guidelines to help keep our waters clean and safe from the golden mussel invasion!
