Big Lake is one of dozens of medium size lakes scattered across the Puget Lowland. Like most of them, it was probably once lined with thick forest and the shoreline was probably choked with fallen trees and drift wood. Now the trees have been cleared, the water levels altered, and the local watershed is filling up with suburbia.
Except on the largest lakes (like Lake Washington), there probably wasn't sufficient wave action to form beaches, and even where there may have been, they would have required sand and gravel and not too many fallen trees. At this little postage stamp of public shoreline on the west side of the lake, it looks like gravel was brought in from elsewhere to create a little beach next to the boat ramp. Without housekeeping, the reeds and the forest would eventually take this site back over.
