Dredging Update IV

Hi all,

Please find attached the weekly erosion control inspection for the Lake Koshkonong Dredging and Shoreline Restoration Project conducted on 02/18/2013. Below are the items of note:

·         Active construction of the berm began on 02/11/2013, and is now 95% complete with some final tie-in work remaining. Dredging operations are currently on hold as Badgerland works to repair the ice road.

·         All erosion control measures in place and appear to be functioning appropriately, including the tracking pad and the silt curtain.

·         Silt sock has not yet been placed in the dredge area and it is no longer practical to do so. As water levels have risen, Badgerland instead built ice roads to connect to the existing silt curtain to provide continuous containment. Silt socks are no longer necessary in the dredge placement area as the berm is now providing containment.

·         I will be leaving a copy of the inspection with Kevin while on site today to add to the on-site file.

·         The National Weather Service NOWData has noted that Fort Atkinson received 0.50" of precipitation, so I will be performing an additional post-precipitation inspection today, with a report coming tomorrow.
