Lake Rotokare has been reopened to swimmers and boaties as levels of a toxic algal bloom have dropped.
Tests by the Taranaki Regional Council show cyanobacteria levels had reduced significantly and all health warnings have been removed. In 2013, a team of experts from Waikato University suspected growing numbers of perch may be responsible for the algae plaguing the reserve.
The Rotokare Scenic Reserve Trust is working with the university to discuss options for fewer or shorter closure periods.
Tests will be done again in two weeks.
