The dock sits at full-pool elevation. At low pool the waterline retreats and the reach to navigable water changes. Scale is illustrative; the 6 ft figure is from published operations for this lake.
Idealized cross-section. Max depth 155 ft, average 50 ft. Depth at a specific dock depends on local bathymetry — verify at the property.

Beautiful clear water and the fishing is genuinely good. Be aware the level drops in the fall and our dock needed a longer walkway than we budgeted for. Not a dealbreaker, just plan for it.
Main channel is fantastic. Some of the back coves get shallow and mucky by late summer. Walk the actual shoreline before you commit, not just the listing photos.
Smallmouth and walleye both fish well. Water clarity has held up over the fifteen years we have been here, which I credit to the watershed protections.
