Stock tank

Dispensing may be regulated by a mechanical float device similar to a ballcock in the tank of a flush toilet.

[2] To provide water to wild animals, not livestock, fencing may be built to surround a trick tank.

Trick tanks are widely used in the southwest United States,[3] where periodic droughts may cause population crashes in game animals unless water supplies are provided.

[7] Another use of a stock tank is at a fair or other event where they are filled with ice to keep canned and bottled beverages, or even perishables such as watermelons.

[8] Stock tanks can also make perfect indoor habitats for aquatic pets, such as fish, turtles or frogs.
