BIG TIMBER CITY OF is one of 123 community water systems in Montana in the 501 to 3,300 people size category, serving 1,650 people from surface water.

As of August 1, 2026, its federal record holds 12 entries between 2002 and 2014, all of which EPA lists as closed. Nothing has been added since 2014.

The record involves synthetic organic chemicals, the Lead and Copper Rule, and the Surface Water Treatment Rules.
