most of the sliders on the delta that were there for years were taken down a couple years ago when they dredged the channels. There are still some that are not permanently built ie. the posts are in the ground and the rails are hidden in bushes but you have to know where to look. I would suggest just making some simple flat bars with some plastic water drums. This summer my buddy wants to spend some time putting in some permanent ones, just gotta get good spots so they dont get taken down.

There is a ghetto one on the Petaluma river.
