Since that time there have been studies by numerous agencies and institutions to evaluate the relationships between upstream water resources development and estuarine environments.
Several studies are currently underway.
There is no doubt in my mind that the estuary is by far the most variable ecosystem in existence, and as a consequence no group anywhere in the world at this time can, with confidence, state the precise needs of estuaries. New models, techniques and ideas are being formulated daily, but no one should be led to believe that it is and easy task. We need research. The worst thing is a decision based on emotions. After research we need to educate the people with the facts and then let the political body make decisions.
