The southern end of the lake occupies part of the Okataina caldera.

The lake is one of the least visited, but offers great Kayaking and fishing (rainbow trout).

It has two access points, Otautu Bay and Kennedy Bay and is well located centrally to many other places e.g. the ocean, mountain biking, hiking etc.

The New Zealand Ministry for Culture and Heritage gives a translation of "turbid lake" for Rotoehu.
