deep water channel access

Hello all, i have been trying to find a spot to launch on the deepwater channel below the port of sacramento for awhile but it all looks private. i checked it out on google and it looks like there are some turn outs with foot paths cut to the channel along jefferson blvd and it also looks like there may be some areas to launch around courtland, can i launch in these areas without trespassing? or do i have to make the long paddle from the port of sac to fish the channel?

I've bank fished on those trails on Jefferson a bunch of times and never been messed with.but I'm not sure you could get a yak down any of those trails tho they are pretty tight

If you got wheels, you can haul your kayak at the end of Marshall Rd in West Sacramento to the DWC. I did that a few times and saved a lot of time. Just a bit of a trip back to the car at the end of the day.
