Batchelor; Finniss River


The findings of the report indicate that the concept of a further storage supply to Darwin based on a dam on the Finniss River at Batchelor would be feasible and that the optimum development programme for the Batchelor Scheme would involve, in sequence, the following works : (i) construction of a pumping station at Hanna's Pool to divert the unregulated flows of the Finniss River through a steel rising main to the Darwin River catchment. (ii) construction of Batchelor Dam to F.S.L. 68 m A.H.D. (iii) construction of a concrete lined channel to transfer water between Batchelor and Darwin River Reservoirs.
