The Harvey Water proposal involves piping the Harvey irrigation area, thus saving water which is currently lost to seepage and evaporation from open channels, and trading the saved water to the Water Corporation for public drinking water supply. In total, about 17.1 billion litres of water (each year) would be saved by the proposal - this includes 5.3 billion litres from Logue Brook Dam. The entitlement for this water would be traded from Harvey Water to the Water Corporation, in exchange for funding for piping the Harvey irrigation district. The Department of Water is receiving feedback from the community on this proposal, and will make a decision after consideration of this information. At this time no decision has been made. If the dam becomes a drinking water source, then current public health requirements prohibit the existing recreational use. (c)(i)-(ii) Water from Logue Brook Dam has been tested by the Water Corporation since 1999, and results for 2004/05 are provided below.

(a)(i)-(iii) - (b)(i)-(iii) The Department of Water are considering a proposal to change the use of Logue Brook Dam from 'irrigation and recreation' to 'irrigation and drinking water supply'. The proposal seeks to establish Logue Brook Dam as a source of public drinking water.
The Harvey Water proposal involves piping the Harvey irrigation area, thus saving water which is currently lost to seepage and evaporation from open channels, and trading the saved water to the Water Corporation for public drinking water supply. In total, about 17.1 billion litres of water (each year) would be saved by the proposal - this includes 5.3 billion litres from Logue Brook Dam.
