Wow! Phil MacFarlane. That's an amazing account of the Delta and quite accurate.
The delta, at least a small part of it, is my home turf. I sail out of Antioch and typically range a few hours east, west, and north on the Sacramento. A few things Phil missed...
On your way up river once you make the right hand turn leaving Benicia, the wind may pickup from the Northwest (18-25mph). The typical summer pattern for lots of wind here is fog on the bay and 90+ temperatures inland. If you are unfortunate and catch the ebb here, the waves get pretty bumpy from there to blind point (about 2 miles past the Antioch bridge). Great downwind sail bumps and all. So save the gas.
Stay in the shipping channel when you pass Port Chicago. Especially if there is ship there. They will remind you of the restriction and show you what an M60 looks like. Also don't stray too far north of the channel (like 9' some places) it gets shallow! Turn right at the Pittsburg power plant -can't miss it- and you will be in New York Slough. Watch for shipping traffic and shifty winds. Exiting NY Slough you will be in Antioch. I have an gray striped E27. Give a wave if you see me. The Antioch Bridge is the next big landmark and of course False River not too far from that. If you don't go through False river, the San Joaquin will turn to the north just past the moored barges (you will know when you see them). Usually a little upwind sailing. Being that far upriver, the wind usually get calm.
My personal favorite place to stay is Owl Harbor.
My wife likes hot showers and clean bathroom facilities and Owl Harbor surpasses in these. I personally like ...the people, that it's dog friendly, they have outdoor movies, fresh eggs and sometimes veggies, and the peacefulness. Call Chris or Devery for a reservation. Tell them the Kiba's sent you.
Some tips on your return.
Leave on an ebb but remember it gets bumpy if the wind is up. The stretch between the barges (east of False River) and the Antioch bridge can get tricky in the afternoon (3:00-6:00pm). If you are north and east of the barges (like coming from Owl Harbor) there is a great short-cut that will put you at the base of the Antioch bridge. The trick is to drop sail and motor through Edos Marina. You may have to check the depth - a friend with a Catalina 30 does this regularly. The other trick is finding the entrance to the shortcut. If you are past the barges - you missed it! Look for the sign on the west shore and... "if you get lost, ask for directions".

The water quality for swimming an relaxing get better further up river.
Have a great trip.
