Agreement 2008-0153-R4; Blach Afterbay Sediment Transport
Document Type
NOE - Notice of Exemption
Document Description
Transfer approximately 400 cubic yards of sediment from in front of the 30 inch low level outlet on the south side of Balch Afterbay Dam to an area behind a floating turbidity curtain on the north side of the Afterbay, using powered suction hoses on a floating barge. Existing roads will be used to access the work area. Fish and other aquatic wildlife will be removed from behind the curtain prior to movement of sediment into that area. Upon completion of the sediment relocation, the water will be allowed to settle to match background turbidity, and the silt curtain will be removed. Turbidity will be monitored before, after and during construction to ensure levels stay within mandated percentages.
