Again we get back to habitat. Yes, that is important. And in the short term that is going to be negatively affected in terms of breeding. But the effect is not going to be as great as people think. Again, if you don't close those weirs, you further degrade the habitat, and you lose that breeding ground. Those species you listed all prefer grassy shallow water areas to lay eggs in. As I stated before, last year at this time, submerged aquatics were a myth in many marshes. Salinities were too high to support it, and in that area of the weirs, lake water was making the problem worse. If you have no submerged aquatics because of salinities, you have no breeding ground.
