Irrigation in South Otago 2001: a feasibility study

Abstract

Irrigation is almost unheard of in South Otago with only a small number of farmers ever using it. Despite being an area that is not traditionally know as being prone to drought, South Otago does occasionally suffer from extended dry periods that can cause production fluctuations, with some parts of the district being more susceptible than others due to soil type, aspect and micro climates. This report will focus on whether it is practical to irrigate on rolling down lands in South Otago. It will outline the climate and then look at the water resource, give an overview of the various irrigation options available, and give an example of a system for my own property.
