Queensland residents draw to the attention of the House increasing community concerns about water security in South East Queensland and increasing support for non-motorised recreational use at Leslie Harrison Dam.

Leslie Harrison Dam was built when Redland's population was approximately 12,500 people, the population is now over 155,000 with Leslie Harrison Dam connected to the SEQ Water Grid. The completed dam improvements by Seqwater saw Leslie Harrison Dam's holding capacity reduced as the dam gates were not re-installed. With the recent rains, the dam is now flowing over the spillway instead of the water being contained in the catchment area.

Redland's water is supplied from combined sources including the aquifer on North Stradbroke Island. Community groups are concerned that the aquifer on NSI (Minjerribah) does not have the capacity to keep supplying over 60% of Redland's water needs without environmental harm to the Island.

No recreation activities are permitted at or on Leslie Harrison Dam. Seqwater manages several dams connected to the SEQ Water Grid that have a holding capacity less than that of LHD and recreational activities are permitted at and/or on those dams.

Your petitioners therefore request the House to:
1. Release the GHD engineering report that determined the dam gates would not be reinstalled.
2. Investigate the feasibility of additional options to restore the Dam's holding capacity.
3. Permit non-motorised recreational use at and on the Dam while having regard to conservation opportunities.
