You have some good points about how other areas of the cascades have glacial reserves to keep the rivers flowing, but the point that I was making is that this is the point that you can see and measure what the available water still is on the soil, since almost everything coming in has not been replenished since the end of June.

It’s not a “point of no return”, but it’s a reasonable benchmark to see how long and intense our summers are by how low the water flow is at Snoqualmie Falls at the end of summer.
