Waikoura Springs

Freshwater Crayfish 

and Poultry Farm

Subtitle

All buildings remained structurally intact. The location is a drained swamp. It is sedimentary soil, suiting a fish farm - but not for resisting a major earthquake.

However our buildings are on an isolated shingle fan, caused by historical flooding of the Kohwai River, a major catchment of the mountain ranges. (FYI this was in pre-stopbank times.) Hence our buildings, and one neighbours, remained intact, while some other homeowners in the street lost their dwellings.

The earthquake lifted the land two metres, which improved the flow rate in Lyell Creek. Thereby it has a better effect of managing water pollution by the dilution method, such as chimney smoke being more readily dispersed on a windy day.
