However, the lake is completely fenced to exclude livestock but cattle have been observed accessing the margins (source www.lawa.co.nz).
Lake Waipara is 2.4 hectares in area and 4.4 m deep. Ringed by a narrow margin of manuka scrubland, a forest road and then plantation pine forestry. No inflow or outflow streams (source www.lawa.co.nz).
