Rotomanuka Lakes Project

The Rotomanuka Lakes are peat lakes situated in the Waipa Region of the Waikato. They are linked hydrologically to the Rotopiko Lakes complex and drain into the Waikato River via Mystery Creek. Therefore the water quality in these lakes has a direct impact on the Waikato River.

‘A Community Catchment Restoration Action Plan for the Rotomanuka Lakes’ is a three year project, delivered with funding from the Waikato River Clean-up Trust over the period July 2012 - July 2015. It aims to target the whole catchment, assisting the farming community to work together as a group to improve lake water quality.

In order to maintain and improve the water quality and the surrounding wetland buffer of the Rotomanuka Lakes, NZ Landcare Trust intends to develop a Community Catchment Restoration Action Plan. This will focus directly on the farms within the catchment. The action plan will provide farmers and agencies working in the catchment with a prioritised list of what actions can be taken to improve the water quality over time e.g. fencing drains and riparian planting. 

An additional aim is the establishment of a Peat Lake Restoration Project map. This map will showcase all the restoration projects happening on peat lakes in the Waikato and Waipa districts.   

Information and progress reports will be posted on this webpage as the project rolls out. For further information contact NZ Landcare Trust Project Coordinators Melinda Dresser and Nardene Berry -  waikato@landcare.org.nz

 


Project Update: June 2013

In October 2012, a newsletter about the project was sent to landowners around the lake and an article was published in the Ohaupo Community News.  A copy of the newsletter is available for download> 

 In November 2012, a Peat Lake Restoration Projects map was developed: www.landcare.org.nz/Regional-Focus/Hamilton-Tauranga-Offices/peat-lake-map

Meetings were held with landowners adjacent to the lake at the beginning of the project where aspirations for the lake and ideas for restoration were discussed.

Whole Farm Plans (WFP) were carried out on the three large farms in the catchment in conjunction with Headlands. Learn more about WFP's: www.landcare.org.nz/News-Features/Features/Farm-Planning-for-the-Future

 

Project Update: June 2014

In November 2013, a successful community planting day was held.  About 30 local people, including many children, turned up during the course of the event, which ran for three hours in the afternoon.

In January 2014, a scoping study was carried out to identify nutrient and sediment “hotspots” entering the lake from inflowing streams and drains.

Eighteen drains and one permanent stream were surveyed, of which all but two, flow directly into Lake Rotomanuka. Ten of the watercourses flow into the smaller South Lake and seven into North Lake. Eight sites were identified as being suitable for infiltration wetlands and four for silt-trap treatment wetlands.

The scoping study and the actions from the Whole Farm Plans are currently being developed into a Community Catchment Action Plan which will be available late July.
