I don't know about Naci in November but in 2007 I did fish it in the fall pretty thoroughly. I caught spots and white bass in to October. The reports are here, scroll down:

1/2oz ice jigs fished in open water under seagulls worked good for me. Any shad pattern vixen / repo man can be good for spots on bluff walls and shade.

Naci goes through cycles in terms of fish size and health. The cycles follow water levels. Low water results in skinny small spotted bass. High water results in fat happy spotted bass.

2007 had really small skinny fish so the lake should be cycling up now.

As far as san antonio goes, this year saw one of the better striper bites in some time there. The fish were 8 to 15lbers. When I was fishing the lake in 2007/2008 these fish were mostly 5 to 7lbers. The fish are fat and healthy. San Antonio striper bite best in the hot summer months. November is probably a crapshoot.

San Antonio is a very strange bass lake. Sometimes you go and catch quality largemouth and smallies no problem. Other times you wonder if there's any bass in the lake at all. Only way to find out is to go.

Margarita is your classic bass lake. It was really peaking a few years ago with good number of fish over 10 being caught. I saw fish to 13lbs in there in 2008 and people have caught a few of them. Don't know what's up now but assume it's on the downside since they stopped stocking trout.

You might go and find some nice hungry 9lbers that used to be 12's. Fish that are starving are generally easy to catch. Just look at what's happening at Coyote right now, poor bass.

As far as the quagmire, you gotta look online and see what the rules are. Always changing.
