When the weather heats up, many want to grab a drink, get on a boat and spend time with friends and family on the water. This year, at Lake Camanche, it’s a different story. “We’ve taken the precaution, a difficult one, to shut down our boat launches for this year as we try to get our arms around this and figure out the best way to prevent its introduction to East Bay MUD’s water system,” East Bay Municipal Utility District spokesperson Christopher Tritto said. The reason is because of the recently discovered golden mussel found in the Sacramento and San Joaquin Delta. While this invasive species hasn’t made it into the reservoir, the utility district is taking this ban a step further: no kayaks, no paddleboards, and more. The only boats allowed are those with a permanent slip or boats that have been in the water before the launches closed.
