Inquiry #5: 1. Plans reference the existing water level of the aqueduct to be elev. 2940.82. Permit 1626 indicates that the min water level during the construction period will be elev. 2935. Please confirm that it is not in the scope of this contract to dewater as there is no bid item to do so. It is assumed that the DWR will perform this work. Please confirm.

Response #1:Department of Water Resources (DWR) will not do any dewatering. There will be No Dewatering of the canal at any time. DWR will lower the water level in the canal between November 15 and December 31 of the year of construction. The cofferdam installation shall be done without dewatering the canal and under partial flow conditions. According to the Encroachment Permit: 1626 Special Provisions 6 through 9, Pool 58 will remain in service delivering water during construction. The lowest water demand period is between November 15 and December 31 of the year of construction, this is when the pool may be lowered down to the 2935? elevation, which is the minimum required to continue delivering water. Special Provision 7 allows contractors to request restriction/reduction on flows, however it will be evaluated on case by case basis, but no guarantees that it will be approved. Outside this period DWR must be able to deliver water with no restrictions on flow or water surface elevation.
