I've been in Texas spending time with my family. all I was getting was text from fishing buds about the mussels showing up here in CA. they were confirmed in the California Delta. now some lakes are at a hard stop. full sanitation before entry. or 30 day quarantine. I'm a kayaker, so I could have a Clearlake kayak, and a Berryessa kayak. haha..
my secret lake is untouched thus far. personally I am careful. I store my kayak wide open after toweling the interior dry. I even put a small fan inside to keep the air moving to desiccate any hitchhikers. even my fishing net is siliconed completely to not trap water.
but I feel it is like trying to hold back water. Clearlake could use about a billion filter feeders. hahahha..
Watercraft are only one source of transfer of "invasive species". Waterfoul probably account as much if not more than boats.
