There is an historical swimming pool actually constructed into the bed of the Kakahi Stream, located about west down Onematua Road from State Highway 4 at the northern boundary of Ōwhango. The pool was created by locals in the hope of preparing one of the local athletes for the British Empire and Commonwealth Games. Beside the pool is a monument marking the centenary of the Treaty of Waitangi. Local records indicate the pool was first ready for use over the 1939/1940 summer. In 1961 a conventional swimming pool in the grounds of the local school was opened.
