I don't think anyone is saying that the low levels are a good thing. Ok, maybe the people behind low bridges. But what can anyone do about the water level? The Lakeport dam is already at its minimum output. We just have to wait for rain.
You don't have to look at stains on the wood to see the lake is down just check the levels at

BTW Last year when they dropped the Lowell dam, I waded from the Nashua boat launch. I was well past the middle of the river before the bottom of my shorts were wet. There is only a narrow channel of deep water, its on the Hudson side there but it does meander.
Orion, the Lowell dam effects the water level upstream, in theory all the way up to the Manchester dam. You're right, it can't effect Winnipesaukee.
