The green left makes up stuff sometimes, Ilikeverin. Ask your standard Albuquerque resident about 'silver minnows' and you are not likely to get a pro-environmentalist response. 
But I am a part of the green left 
Well, look at my comments in the open D4 thread for more on that. I would like to say that the worst thing the green left has done in NM is their deliberate targeting of poor, struggling family ranchers for lawsuits in order to financially ruin them...seems I have some of the Sagebrush Rebellion in me after all.
Those aren't the green left, they're the green evil
(Actually, they don't seem that green; if they were, they'd be targeting the evil huge livestock farmers whose excess crap (yup, animal wastes 
) runoff into the rivers and cause algae blooms, leading to fish kills due to lack of oxygen.
Shall we move this to another thread?
Well, there's nothing like watching Santa Fe upper-class liberals trying to shaft rural working-class populists to irritate me.
And you are talking about Non-Point Source Pollution, right? I did a paper on that very topic back in graduate school in 1998 (well, part of a long paper on water stuff, but non-point source water pollution was far more interesting than the other parts), and would like to add that sometimes the pollution breeded parasites who killed the fish in large quantities. Ah, memories...
