Without knowing what the bid documents identify, I would say that the following would be the areas:

Area 1 - from the lake front south to just past the Bitter End - this is the shallowest part of the canal - plus the narrowest.

Area 2 - From area 1 to the last canal south of Anchor Point Marina

Area 3 - From the last south canal of Anchor Point Marina to the gas docks of Mienke Marina and up to the canal that goes into the east section of Mienke Marina (old Flietz Marina)

Area 4 - It is either the canal from Cooley Canal west to the public launch ramps of Lucas County or the rest of the canal from the east section of Mienke Marina south to the road

All of these areas combined add up to .67 miles
