Beating the dam builders

Heiko Bleher visits a stream about to be dammed and discovers many fish species.

The aquarist is one who must learn the ways of the biologist, the chemist, and the veterinarian. [unknown source]

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If youíre going to take it under your wing then youíre responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]

Dams aren't as ecologically friendly as most people would have you believe. They impede the movements of fish like sturgeon and salmon from freshwater headwaters to the ocean. They also block freshwater fish from returning to spawning grounds upstream. Not to mention the siltation and changes in water parameters below the dam. I wish more decommissioned dams could be removed.

I am all for removing decommissioned dams, but that may not turn the stream back into its original state. By creating a catchment pond you will have sedimentation building up in that area. Also if species displaced by the dam have no habitable waters to retreat too, then they can not repopulate once the dam is removed. If you live in more developed countries, most of your rivers are far from natural and were damed up long ago. The town I currently live in is called River Falls, the falls I assume use to be were the 2 dams are now. The upper and lower portions of that river are pretty well protected, but that's mainly because its scenic and its a class 1 trout stream.

This situation will be repeated over and over again. Those of us in more developed countries may take water for granted. But fresh water is expected to be the next big limiting factor for human population and its already been a major or contributing reason for some past and present conflicts between humans. Unfortunately FW fishes will only be pressured more in both rivers and lakes. Sport fish at least stand some a chance, you can't say the same for species that don't have much of an economical value.

.... I'm probably drunk.

This is how I lurk
