Storage Dam for Pump Irrigation Water
New Zealand Journal of Agriculture
15 January 1959
[N.Z Forest Service photos by J. E. Johns Three needs, electricity generation, water conservation and stabilisation of run-off, and preservation of native protection forest, are all served by the Cobb River dam development in Nelson. These two illustrations (reproduced in colour on "Journal" covers in July 1955 and for this issue respectively) show how the river behind the dam has been converted into a lake ringed by native forest consisting mainly of silver and mountain beech. Preservation of native forest, alpine shrubs, and grasses in the catchment area to check erosion is a feature of the Cobb development. The hydro-electric station has a capacity of 32,200 kW.
