Seasonal prediction of lake inflows and rainfall in a hydro-electricity catchment, Waitaki river, New Zealand [PDF]

open access: yes, 2010
The Waitaki River is located in the centre of the South Island of New Zealand, and hydro-electricity generated on the river accounts for 35-40% of New Zealand's electricity. Low inflows in 1992 and 2001 resulted in the threat of power blackouts. Improved
