Lake Wilkie
Lake Wilkie is a small, scenic lake near Tautuku Bay in the Catlins, south of Dunedin, New Zealand. It formed after the last ice age and has gradually shrunk to its current size of 1.7 hectares (4.2 acres). Bog lakes like Lake Wilkie are a rare ecosystem in this part of the country. ==Formation== Lake Wilkie was formed after the most recent ice age about 13,000 years ago. Trapped towards the coast by a small cliff, water accumulated in a depression between ancient sand dunes. Originally, the lake was much larger and is slowly being filled in and reclaimed by the vegetation around it. Today, the lake is very shallow and its water colored brownish by organic acids released by the peaty soils.〔Department of Conservation NZ information panel along walking track〕
