The boat ramp at Ngamimiro Bay (also known as Kennedy Bay) is one of two public launch points on Lake Rotoehu, accessed off Pongakawa Road.

It serves as the more formal ramp on the lake and is commonly used for larger craft, while several informal launch spots also exist along State Highway 30.

Lake Rotoehu is a small, scenic freshwater lake featuring eight sheltered arms surrounded by native bush and wetland vegetation. It supports a well-regarded rainbow trout fishery, with fish averaging around 1. 5 kg.

The lake is best fished in autumn, winter, and spring, as summer algal blooms can hamper conditions. Fishing by small boat or canoe is considered safe on the lake's calm waters.
