What the numbers are, and are not

Drive times and road miles are one-way road routing from downtown Cincinnati to the nearest public road at each lake, over the OpenStreetMap network via OSRM (router.project-osrm.org) over OpenStreetMap, driving profile, free-flow. Free-flow means no traffic model and no time of day, so a weekend morning will beat these numbers and a Friday afternoon will not.

The letter is the lake’s A–F water-quality grade: clarity, total phosphorus and chlorophyll-a measured over years, not a rating of the beach, the boat ramp or the view. An A describes the lake’s record; it does not clear the water for a particular afternoon. Lakes with no letter are not listed here, because the letter is the only axis this page ranks on.

Size and access come from the lake record where the agency published them. “Not recorded” means nobody documented it — it is a gap in the paperwork, not a statement about the lake.

By road, from downtown Cincinnati to the nearest public road at each lake, over the OpenStreetMap road network. They are free-flow times: no traffic, no time of day, no stops. Treat them as the floor, and add for rush hour and for the last stretch to the water.

No. The letter summarises years of phosphorus, nitrogen, algae and turbidity measurements — it describes the lake, not this afternoon. A beach closure, a bloom, or a heavy rain can change conditions on an A lake overnight. Check the lake's own page for its measurement record, and check the managing agency for current advisories before you get in.
