Central Otago Mirror - - CONVERSATIONS - Wa­ter quan­tity, qual­ity and the Falls Dam A big thank you Not ac­cept­ing news

Th­ese top­ics, which are all cur­rently of high in­ter­est, seem to me to be linked. At present they’re be­ing treated as sep­a­rate is­sues; a path that is un­likely to give the best out­come.

The quan­tity of wa­ter (wa­ter flow) has a di­rect ef­fect on wa­ter qual­ity in two ways. First, a fast flow cleans out the river and moves pol­lu­tants out of the river quickly. Sec­ond, a greater wa­ter flow keeps the wa­ter tem­per­a­ture down and lim­its al­gae growth.

In the case of the Manuherikia River, the Falls Dam stores wa­ter which is re­leased when the wa­ter flow drops. In­creas­ing the height of Falls Dam would al­low for greater wa­ter stor­age and as a re­sult in­creased wa­ter flow. This would be of most ben­e­fit in our dry sum­mers and mean farm­ers could con­tinue to draw wa­ter as they do now and recre­ational users (fish­ers, swim­mers, kayak­ers etc.) would be able to safely use the river for plea­sure through­out the sum­mer.

Treat­ing th­ese three top­ics sep­a­rately slows the de­ci­sion mak­ing process and in­creases the risk of a de­ci­sion on one topic ad­versely af­fect­ing the out­come for the oth­ers. Surely the most sen­si­ble ap­proach is to get all the play­ers in the same room and to­gether work out the best way for­ward. The out­come would then be a solution that is based on a bet­ter un­der­stand­ing of the needs of each group and a plan to achieve the best pos­si­ble out­come for the whole com­mu­nity.

While shop­ping at our lo­cal New World, I lost a large sum of money prior to the check­out. For­tu­nately, a very kind per­son had handed it to the kind women who were serv­ing. A big thank you from me and as they say, I was able to ‘‘bring home the ba­con’’.

I was in­ter­ested to read the opin­ion piece by Cen­tral Otago mayor Mr Tim Cado­gan ( Mir­ror, May 3).

I agree com­pletely with his very rel­e­vant warn­ing to us, to ‘‘not ac­cept what poses as news at face value’’.

Mr Cado­gan quotes Adolf Hitler’s phi­los­o­phy for ma­nip­u­lat­ing the masses: ‘‘Make the lie big, make it sim­ple, keep say­ing it and even­tu­ally they will be­lieve it.’’

I won­der how many of your read­ers could see ex­am­ples of this hap­pen­ing in New Zealand?

I im­me­di­ately thought of a glar­ing ex­am­ple in the way many of New Zealand’s lead­ers and thought ma­nip­u­la­tors have vig­or­ously en­cour­aged us to de­value and ig­nore the rights and feel­ings of young New Zealand chil­dren in the womb.

The nar­ra­tive says that they are not re­ally hu­mans (‘‘the big lie’’). It’s just a bunch of cells (‘‘it’s sim­ple’’). We have heard the nar­ra­tive for decades (‘‘keep say­ing it’’). Then we have New Zealand at­ti­tudes to­day (‘‘even­tu­ally they will be­lieve it’’).
