"I think [this thing] is evil, convince me I'm right" is, in a nutshell, what you ask. There are indicators (i.e. using the word dumping) showing us this. This means, objectively, you are pushing an agenda, which by the rules of this SE, is discouraged and a VtC reason.
Your question could be one that is kept. Instead of coming here and bitching about your closure (see what I did there? contrast if I had used 'discussing' vs 'bitching'), take the time to attempt to be neutral, in word choice and tone.
Yes, you have an agenda, but we don't want to hear it, and spending time answering it would be, as learned over the years, fruitless. You are looking for a "yep, you're right, they should sell the water" and any other answers would have you find fault with the answer in the comments. This has happened many many times.
Now, maybe you're not that person. Maybe you really, truly, want to know what you ask. But experience shows you are simply wanting your point of view enforced, enhanced and proven correct.
Coming to Meta and asking "why was my question closed" and then getting answers, but not accepting those answers, is not helpful. Here is my advice to you, and anyone else asking this kind of question and wondering about closure: Stop telling us why the reasons we give are invalid and accept them as truth. They are why your question was closed. (Are they really? I obviously can't speak for anyone else' thought processes, but I'm asking you to accept it AS truth.)
Now that you have been told the reason(s) why your question was closed, stop arguing that our reasons are invalid and correct your question.
Remove the obvious bias. (dumping vs releasing)
Don't give your answer within your question (money/profit/selling water).
Just ask as neutral a question as possible. (The Feds have decided the basin is to be simply released into the ocean. Why was this done and what are other choices?)
Reiterating myself one more time, coming here and asking why your question was closed, and then arguing that the reasons given are invalid does not cause people to want to VtRO. Accept the reasons as valid, whether you agree with them or not. Fix your question, then when you've edited it, it should come up in the review.
