Creating a good map of the depths will be a big help in future management. You and the owner may be surprised to learn the real depth of the organic sedimented rock pit. Without good aeration it could easily have accumulated 1"-2" of dead, organic, muck-slop per year.
Water of 18 ac will take lot of money to fix problems, maybe not soon but not to far distant. If a big portion of the area up from the rock pit is less than 6ft deep then this could be a water weed or algae nightmare and costly to treat at 18ac size. Plan on the near term budget to some late summer, fall drain it down to lower pool to probably the location of the top of the old rock pit. Let dewatered areas dry, and then late fall or winter deepen the edges and the shallow, inlet end basin as much as you can afford. I would negotiate a lower property cost due to the lake being more of a liability than an asset due to its current aged and filled in shallow condition which will be costly to deal with, maintain and get FIXED. In its current condition it could be a money pit.
