taking yaks out to grapevine in am, sandies still near silverlake marina??

taking son out in am to chase sandies at grapevine. are they still hanging around the marina / islands? any help appreciated.

thanks so much,

Anyone have an update on this? I know the lake is low, but I'm also curious to know.
Last time I was there the year before I couldn't stop catching them. I finally got the boat running again and am heading out in the morning, still trying to decide on where to good..... Grapevine, Joe Pool, or Arlington.

I haven't been out recently on grapevine but I would check wind blown banks in about 5 - 10' of water.
