Additional Notes
Also see the aerial video linked on the "Videos" page, at left.
The lowest water level achieved during the draw down of 2001 was 1651.41 ft on August 7th. Prior to 1964, the height of the reservoir reached lower levels on several occasions. See this graph for more information.
It is estimated that the height of the top of the old wooden crib dam is in the neighborhood of 1658 ft. It is located in the narrow pass between the main flow and the bay near the current dam. This KML file shows its approximate location. With the typical yearly lowest levels only approaching 1664 ft, the old dam should never be a hazard. It is also visible in the "Drawdown Composite" image, the aerial video taken in 2001, linked on the "Videos" page (approximate time: 2:10), the ground footage video, and the contour depth data layers.
