When the golden mussel was discovered near the Port of Stockton in late 2024, lakes and reservoirs across Northern California imposed new rules on boaters to try to keep the invasive species out. EBMUD, the water supplier for most of the East Bay, took no chances, banning all boats from entering its reservoirs. On Sunday, after more than a year, they began inviting boats back to the water, but they’re being very careful about it. … EBMUD has decided the most effective action is a 30-day quarantine. After an inspection to be sure they’re completely clean and dry, boats will be tethered to their trailers with sealed cables to prevent them from being launched. After the waiting period, they will be allowed back on the lake and then, upon leaving, given another sealed tether, specific to San Pablo.
