Ideas are usually based on assumptions. Sometimes the best way to see whether an idea works or not is to dig deeper than the idea itself and test whether the assumptions are true or not.
For example, the KBRA’s dam removal proposition is based on the environmental and tribal assumption that dams along the Klamath river are the cause for lower fish populations during the 20th century. This argument assumes that had dams never been put along the Klamath river fish populations would have remained the same (higher than today). Moreover, the argument also assumes removing the dams now will return fish populations to a level reported before dams were built along the river.
On the other hand, there is an argument against dam removal which is based on the assumption that there are other, significant reasons for lower fish populations. These arguments assume that what happens while fish are in the ocean for four years matters just as much, and perhaps even more, than what happens during their journey along the river. This argument assumes making the river pristine as the wind drive snow won't matter much because the major issue isn't being addressed — what happens to the fish when at sea?
Neither of these assumptions are spoken about much. Instead action is the word of the day. We must do something now to save the fish. But really that is just silly-talk. If your house was burning down and the fire crew pulls into your drive way you don't want them to do just something. If that were the case, they might start watering your garden to protect it, or digging trenches around your house to prevent the fire from spreading. Worse yet would be if they poured gasoline on the fire thinking that might help. Perhaps some fire "expert" has a theory that adding enough gas to the fire will cause a massive explosion that will temporarily remove oxygen from the area and starve the fire. No. You don't want the fire crew to do just something; you want them to do the right thing. That's why it is highly important that the fire crew fully understand your fire before moving into action. And this is exactly why much of a fire crew's down time is spend understanding the nature of fire and the different types of fires so they can make the right decision when called upon.
While that illustration may seem simple, it still applies to our river, fish and dams. We don't need our leaders to just do something now. We need them to really make sure they understand the problem — the real reason(s) for lower fish population. If they don't and just take action, some “expert” might drive us to throw gasoline on the fire and then we'll all be without.
