That tank might work well for Water Snakes. There's a local nature center that has garters in a big enclosure with other species of reptiles and amphibians (painted turtles, bullfrogs), but I think that sort of thing would be tricky to maintain.

I've kept Black Rat Snakes in a 55 gallon as a pair and they were great display animals - though most types of rodent eating snakes spend the majority of their time hiding.

I built this "natural" setup for my pair of Baird's Rat Snakes and they remain hidden 95% of the time.
