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.

Each lake’s water-quality readings, phosphorus, nitrogen, chlorophyll-a and turbidity measured over years by state and federal agencies, are on its own page. They describe the lake’s record; they do not clear the water for a particular afternoon, and they say nothing about the beach, the boat ramp or the view. Lakes with no nutrient or algae reading on record are not listed here, because the water 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 readings summarise years of phosphorus, nitrogen, algae and turbidity measurements; they describe the lake, not this afternoon. A beach closure, a bloom, or a heavy rain can change conditions overnight. Whether a lake is safe to swim in is a call for the state water agency and the county health department: check the lake's own page for its measurement record, and check the managing agency for current advisories before you get in.
