Gold Creek Pond was formerly a gravel pit that WASDOT used to harvest material for highway construction in the 1980s. It takes up approximately 90% of the floodplain (shown in blue) and is approximately 50 feet at its deepest point. Because of its depth and size, the pond disconnects Gold Creek from a significant amount of water entering from the eastern side of the valley.
Some of the water entering from the eastern side is redirected in a channel (shown in yellow) that WASDOT created when they were utilizing the gravel pit. The remaining water enters the pond and then exits through a man-made outlet (shown in red).
The depth of the pond is a significant part of the problem. As a rule water moves in the path of least resistance, which is the lowest point in its path. At a depth of 50 feet, Gold Creek Pond is the lowest part of the floodplain and it pulls water away from Gold Creek.
As a result, in drier months of summer there is not enough water to keep the creek wet and it becomes disconnected.
