Back in the 80s, when I lived near Sausalito, one free Saturday I visited the US Army Corps of Engineers Bay Model. It is a huge and incredible scale model of the hydrology of the whole Bay Area and a part of the Sacramento-San Joaquin river delta. It is larger than a football field. The day I visited there was almost no one else there and I got a leisurely two hour tour.
I have read that, today, it is very popular with long lines.

There's a similar large scale (~200 acres) model of the Mississippi River Basin https://friendsofmrbm.org/
There's also the not-maintained (because outdoors and no longer used) Mississippi River Basin model, built near the site of a WW2 POW camp in Mississippi. Italian and German POWs provided the initial labor for site preparation.
It covers 200 acres (~80 ha), vs 1.5 acres for the Bay model.

If you have an interest in going (I've never been despite growing up in the area and having family there still), I would advise waiting for cold weather - it is perfect snake habitat, and water moccasins are both venomous and relatively aggressive.
