Document Description
Proposed improvements include cutting and removing four large sections of the concrete dam, filling and reshaping the eroded plunge pool and adjacent northern upstream (west of the dam) and northern downstream (east of the dam) banks to focus streamflow back towards the centerline of the stream channel and through the newly cut dam sections. The southern bank on the downstream side of the dam would be filled with soil and reinforced to protect archaeological/cultural resources. The rebuilt and reshaped banks would be lined with rock and riparian plantings to armor the newly restored banks.
