Lake Waahi (or up to 1913 sometimes called Lake Waihi)^[1] is located immediately to the west of Huntly, in the Waikato Region.^[2] Lake Waahi is a riverine lake, which links to the Waikato River by way of the short Waahi Stream.^[3] The smaller Lake Puketirini lies immediately to Waahi's southeast.

The lake has a maximum depth of five metres and the open water covers approximately 522 hectares,^[2] though the lake extends further through marsh and fenland.

The lake is situated within predominantly pastoral land.

Pollution

During the 1970s the lake had a healthy cover of macrophytes, but by 1981 the lake became supertrophic, with high turbidity and microscopic algae. Monitoring to 2004 showed no significant changes.^[4]
