Both Cedar Island Lake and Tull Lake Central Basin; White Lake Township sit in Michigan. A same-state comparison strips out the state-level water-quality regime as a variable: any grade differences here are about the lakes themselves, not the agencies grading them. The grades are meaningfully apart: Cedar Island Lake grades a B while Tull Lake Central Basin; White Lake Township grades a D. That two-letter spread reflects real underlying differences — different watershed inputs, different depth profiles, or different monitoring rigor.
