An unusual dredging project defined as a “science project” on Whitefish Lake won narrow approval from the Whitefish City Council on Monday. To rid Bay Point of an excessive silt accumulation, the Bay Point Homeowners Association asked for a major variance to dredge the marina. The plan is to suck out 1,800 cubic yards of silt and pump it a half mile across Dakota Avenue to the Murr gravel pit for disposal.
