There’s one in Soda Springs, ID that actually is on a timer. The town is named after a natural soda water spring near by. They were digging a well hoping to provide hot water for the town swimming pool (town is just down the highway from Lava Hot Springs) and ended up hitting a pocket of highly pressurized carbonated water. The new well was capped and put on a timer, the worlds only “captive geyser”: https://www.sodaspringsid.com/recreation/geyser_park/index.php
