OKOBOJI CAMP OWNERS COOPERATIVE is one of 1,221 community water systems in Iowa in the 500 or fewer people size category, formerly serving 103 people from groundwater.

EPA's federal records list this system as inactive in 2023; the record below is historical.

As of August 1, 2026, its federal record holds 11 entries between 1980 and 2000, all of which EPA lists as closed. Nothing has been added since 2000.
