Waitetemoroiti (Loch Katrine) is a small, glacially formed, high country lake located in Lake Sumner Conservation Park, in the upper Hurunui River catchment (www.lawa.org.nz). The lake drains to Lake Sumner through a wetland and narrow channel. It can separate into two basins at low lake levels. Loch Katrine acts as a boat harbour for both Loch Katrine and the adjacent Lake Sumner. The community of holiday homes located beside the lake as well as the relatively high boat traffic are potential nutrient sources to Loch Katrine.
Loch Katrine is framed by beech forest on one side, and low producing grassland on the other, and its beaches are mostly steep shingle (www.ecan.govt.nz).
