Dogs are prohibited from swimming in the lakes.

Dogs must be leashed on all footpaths and roads, and also around the the lakes. Dogs may be kept under effective control on the grassed banks before the lakes.

Lake Tahi

The first lake, closest to the entrance, is leased by Canterbury Jet Sports Club(external link) and is reserved for club members only. All watercraft using this lake must be registered with the club.

The Canterbury Jet Sports Club(external link) website has membership options as well as a comprehensive list of rules, regulations and prohibitions regarding use of watercraft in the reserve.


Vehicles with watercraft must use the access gate at the northern end of Sawyers Arms Road.

Lake Rua

Lake Rua, the second lake, is managed by Christchurch City Council Park Rangers and is a public lake popular for swimming, dragon boating and sailing. 


Access to Roto Kohatu is off Sawyers Arms Road. 

Gate times

Gates open from 7am to 7pm.  During daylight saving months, gates are open from 7am to 9pm.

Gate closures are administered by ADT security. Ring ADT on 0800 766 700 to release a vehicle. A callout fee will be charged to release vehicles at owner's expense.


Swimming is permitted in marked areas only.

Do not dive, or use powered watercraft. There are many underwater hazards from when the site was a landfill such as tree stumps, cars and concrete.


Take an easy stroll around the Lake Circuit Walk, a 2km walk past Lake Tahi and around Lake Rua.
