I guess you probably wouldnt think the same way if you owned a house on the lake. I dont own on the lake but I have many friends that do and none of them I consider to be greedy.

As far as the lake goes, I dont know why they just dont keep it filled and occasionaly drain it in the fall/winter months and around fish runs as needed for maintainance.

Here are a few links that you might want to look at to have a better understanding how the water enters and exits Lake Tapps.
