    Abstract In March 1996 a scoping study exploring the relationship between the
    Southern Oscillation Index (SOI) and stream flows in Wellington’s water
    supply catchments was completed.

    A relationship was established, and it was concluded that it is possible to
    issue forecasts up to one season ahead.

    Based on the scoping study findings, recommendations for future work
    and more comprehensive analyses were made. This report presents this
    further work. For a full explanation of the SOI, data sources and statistical
    techniques employed, the scoping study should be consulted.
