These photos show what the Rotorua lakes on a good day with no wind. Most of the lakes except Lake Rotorua are in at least a reasonably good state as far as water quality and pest invasions go. Unfortunately all of the people involved with looking after the lakes, Te Arawa Lakes Trust, Bay of Plenty Regional Council and all of the scientist need to be constantly vigilant against threats to this balance. Pest catfish are currently infesting Lake Rotoiti and threatening Lake Rotorua by entering the Ohau Channel and water quality in some of the lakes has been slowly declining over the past few decades. Fortunately everyone is mostly on the right page and programmes are in place to deal with the problems, and progress is being made on some issues. But this costs money, sometimes lots of money. In the case of the catfish invasion one careless or nasty person will cost ratepayers and taxpayers 100s of thousands of dollars to deal with the problem.
