SEQ036-14 Lake Kurwongbah

1) ANONYMISED registered access complaints for both lake Kurwongbah and Lake Samsonvale.

2) The COMPLETE engineers report regarding work to be carried out on Lake Kurwongbah dam wall, including reasons for initial wall inspection, and engineers report explaining findings of the inspection and the work that is required to be carried out.  The request also includes the engagement document setting out the parameters for the engineers study.

3) The COMPLETE risk analysis which concluded that concurrent shared access for paddlers and skiers on Lake Kurwongbah is too dangerous.  The report should detail all risks, their likelihood and consequence, mitigating factors and residual risk. The report should explain reasoning of the dangers of concurrent shared access, the lower water level and all information explain investigation, findings and conclusions. The report should comment whether the proposal for a dedicated paddling area was

considered and whether the policy regarding shared access on Lake Kurwongbah is consistent with policy on other Seqwater lakes.

4) The COMPLETE peer review report of the Seqwater risk analysis for concurrent shared access.  This might have been provide previously in document "Principle Seven - Lake Kurwongbah Risk Assessment Review letter Release.pdf ".  If this is the case, then please confirm.  The peer review document included the statement "A club member as already advised of a near miss involving a paddleboarder who was illegally on the lake.  This occurred when the lake was near full supply."  Please provide details of this incident.  As I understand things a person wearing a black wetsuit was noted paddling across the lake while LYING down on a surfboard.  There was no near-miss.  The member drove over to the person and advised that they were difficult to see and the person apologised and paddled away from the skiing

area.  As far as I know, no other people have been seen lying down on surfboards on the lake.

5) The water quality report on Lake Samsonvale on which the decision to disallow further paddlecraft access to that lake.  The report should advise whether the existing access to Lake Samsonvale by several hundred paddlers was taken into consideration.  The report should consider whether secondary contact nature of paddling was considered.  The previously supplied data dump of various pathogen levels in various lakes was of limited value.

6)  The COMPLETE analysis on which the community preference for paddlecraft was derived.  If document " Lake Kurwongbah Survey Statistics.docx" is the COMPLETE analysis, then please confirm.
