water NOVEMBER 2011 11 Dear Editor, I am writing in response to the letter, "Learning To Live With Nature" from Steve Posselt (Water Journal, August 2011, page 12). In 2008 I submitted an application, and was eventually accepted as a presenter, to Enviro 08 with my paper titled, Aquatic Ecosystem Productivity Relies on Water Managers and Sustainable Cities. I went on to present this same paper (updated) at Riversymposium 2009. I do not have a science degree and am not an expert at presenting, but I am frustrated at the failure of my community to acknowledge the impacts on my industry. The commercial fishing industry in New South Wales has been reduced, removed, restricted and confined progressively over the 30 years that my family have been involved with it. It has been reduced from around 4000 fishers to close to 1200 fishing businesses today. It is this way because of the constant debate about sustainability and productivity. Suicide, depression, anger and frustration are common in the industry. Intellectual knowledge has been lost with the demise of historic fishing families. Australia is becoming more and more reliant on imports of fish to our country, while the commercial fishing fleet is being blamed constantly for any depletion and sustainability of our country's fish stocks. I thank the AWA and Steve Posselt for his letter. You have restored some of my faith in my own beliefs and the world of water and catchment management.

Dear Editor, In 1985 there was a Clarence River Committee which held seminars and the like about the famous Clarence. Following these events, a steering committee was formed with representatives from several interest groups funded by the then Maclean Shire Council. Around the same time, the New South Wales State Government foreshadowed the Total Catchment Management Committees, which subsequently came to exist and still exists. Between the steering committee's time and the current status quo, the Clarence Environment Authority was created. Various interest groups, including local government and the Clarence River Fisherman's Co-operative, provided funding. Around 1989, when the Total Catchment Management was created, the Clarence River Environment Authority (CREA), of which I was chairperson, closed down. The CREA did a lot of research, which remains in my possession. The Total Catchment Management Committee, when offered this research without cost, declined to accept it. In the research, submissions by the Fishing Co-operative and the Primary Industry Department were examined. Clear from the research was evidence of major variations in catches of all species of fish from one year to the next. Also clear was a seven-year running average since records began in 1946 remaining effectively constant. The bulk of flood mitigation took place in the 1970s. Work was effectively completed in 1976 with the Maclean levee. Obviously flood mitigation did not change fish catches. Fortunately professional fishermen are aware and realise that a finite fish yield divided among fewer fishermen produces larger catches per fisherman. That awareness is now driving the licence number reduction efforts. Over many millenniums the balance between people numbers and other environmental factors comes from wars and bubonic plague. That method of "living with nature" seems to have worked. It seems to me that while a return to such systems of population management is alright for Steve and/or the Greens, it will not sit well with the high proportion of people whose very existence would need to be sacrificed. In recent times, management of flood gates and construction of a large culvert in the Romiaka Channel area have reduced stagnation with little objection. All civil engineers have duties to look after all people as well as the environment. A new wave of would-be dam busters threatens more damage than benefit. How best to provide for people and the environment should and will always, quite rightly, continue to be examined and debated.
