Little Walnut Creek, Ohio
13.8 mapped river miles, draining 38 square miles, in the Upper Scioto basin watershed. No gauge stands in it; the nearest is 13.6 miles away, and it is the only temperature evidence on this page — what Ohio EPA publishes is the aquatic life use below — a habitat designation under Ohio Administrative Code 3745-1, which describes the assemblage the water holds rather than the temperature it runs at.
50°F and colder is cold, through cold-transitional and cool, to warm above 70°F — the same four bands, breaking at 58, 64 and 70°F, that the app paints. Grey is water nobody has measured.
The nearest live reading
The nearest gauge is 13.6 miles away, at Alum Creek At Africa Oh — not a reading of this water, but of what the region is doing today.
Thermal classification
There isn't one. Ohio EPA publishes no temperature classification for any water in Ohio. What it publishes is the aquatic life use below — a habitat designation under Ohio Administrative Code 3745-1, which describes the assemblage the water holds rather than the temperature it runs at — so this river draws grey on the map above, and grey here means unmeasured rather than warm. The only temperature on this page is the live reading from the nearest USGS gauge, 13.6 miles away; it is a reading of that water, not this one.

Ohio EPA classification
Ohio EPA classifies this water as Coldwater Habitat, Exceptional Warmwater Habitat, and Warmwater Habitat. More than one class appears because the classification changes along the river.Where it changes is on the map above, not in this page's tables: Ohio EPA publishes no temperature classification here, so nothing on this page is drawn from the class.This is Ohio EPA's description of the aquatic community the water supports, assigned under OAC 3745-1 on fish and macroinvertebrate survey scores. It is not the season and creel rules — those are the ODNR Division of Wildlife's, change yearly, and live with that agency.
