The Committee at its first meeting, met and resolved to extend its name to the Brisbane Water Plan of Management and Catchment Management Committee so that the context in which it was carrying out its work was not lost. In the Committee, Sub-Committees, and Task Group meetings, the open Committee system was used with the Committee only being confined to appointed members when confidential matters had to be discussed. Visitors were encouraged at all other times and input was always taken from persons or organisations who had contributions to make. Representatives from Government Authorities were also co-opted to assist where their expertise and in all cases the spirit of involvement was excellent. (iii) Detailed Technical Studies The Committee found that it was necessary to arrange for some detailed technical studies particularly in the area of the current depth of Brisbane Water to enable it to determine the rate of sedimentation and whether the channels in Brisbane Water had substantially changed over the years of human settlement. A request was made of the previous Public Works Department of the NSW Government as to whether such a study could be carried out. Funding was granted to assist in carrying out this study. The water depth studies had shown that a large number of hydrographic surveys had been carried out at intervals throughout Brisbane Water but most of these studies related to minor projects either proposed or carried out over the previous 50 years or so. Fortunately, an extensive hydrographic survey had been carried out of Brisbane Water in 1901 which had used very carefully planned and detailed survey control and an excellent coverage of the depth of Brisbane Water and its bays and tributaries. The study designed for the Brisbane Water Plan of Management Committee's work was to carry out a similar extensive study of all the depths of Brisbane Water and then compare these depths with the depths that had been determined in 1901. This work was carried out using the latest electronic measuring devices and the resulting work was compared with the 1901 work by comparing cross sectional data from the two studies between known fixed points and observing the differences in depths that were found. Comparisons of the accuracy of the different work were made. It was found that there is little difference in the depth of Brisbane Water between the two studies except in the areas where the sediments within the channels have been dredged or have been moved by the fast running tidal current. This finding was contrary to the belief of many of the Committee members as there has been a general feeling that the centre of Brisbane Water is considerably shallower than it was many years ago, however the documentary evidence is quite conclusive. A further technical study called the Brisbane Water Environmental Study was carried out to determine the water quality and the quality of the sediments in Brisbane Water. Whilst this study did not address the main issues of the Stage 1 work, it was seen as an essential background study to the Stage 2 work and should be carried out at an early time. A study was required over an extended period to get the full knowledge of the seasonal variations in water quality. The work on the sediments was necessary to tie in with the sediment studies being carried out as detailed above. The water quality work was designed to carry out sampling and testing to show whether there was a profile or gradation of water quality from the outlet of Brisbane Water to the upper reaches of the various major tributaries of Brisbane Water and was designed to enable the Committee or later Committees to be able to determine where further works should be targeted to overcome any problems that might be found. The sediment studies also enable an examination of the nutrient levels in the bed of Brisbane Water and was also was able to Brisbane Water Plan of Management - July 1995 Page viii
confirm the geological or geomorphological structures of the various areas of the waterway. These technical studies enable the Task Groups and Sub-Committees to have a much better understanding of the way in which the waterway operates. (iv) The Committee's Methodology of Assembling the Plan of Management Report Numerous Task Group and Sub-Committee meetings were held and their progress regularly reported to the Plan of Management Committee. Progress reports prepared by the Task Groups and Sub-Committees were discussed and the Sub-Committees were modified accordingly. These efforts were mostly co-operative and collaborative although at some times the Task Groups and the Sub-Committees did not agree with the viewpoints of the main Committee. Some of these reports were somewhat contradictory and whilst at the time this was seen to be problematic, the Committee resolved that the documentation presented by the Task Groups and Sub-Committees would be presented as an appendix or working document for the final report so that the Committee does not loose sight of the different viewpoints of the Sub-Committees and Task Groups. In order to prepare its final report, the Committee then refined the reports of the Sub- Committees and Task Groups and attempted to remove the anomalous viewpoints and at times substitute the Committee's own viewpoint in reaching what the Committee believed was the best alternative for the Plan of Management. Also throughout the Committee's work, the Council resolved to develop a new Jetties and Wharves policy for Brisbane Water as it was having difficulty with wharf proposals that were being submitted. As a result, the Brisbane Water Plan of Management and Catchment Management Committee had considerable input into the preparation of the Jetties and Wharves Policy which is now included in this document as part of the Plan of Management proposal for Brisbane Water. A Sub-Committee was created for interacting with the community in determining the new Policy which included community representatives who were wharf owners and who were involved in the wharf industry in the Brisbane Water area. Finally the wharf proposal put forward by the Sub-Committee was forwarded to the Brisbane Water Plan of Management for comment. The Brisbane Water Plan of Management Committee offered some amendments to the policy which was put forward to the Council and a policy was adopted. It is the adopted document that is included in this draft Plan of Management. Brisbane Water Plan of Management - July 1995 Page ix
