BirdTrout
Grand River Watershed, Ohio
1,936 miles of mapped stream across 706 square miles of drainage in Ashtabula, Trumbull, Geauga, Lake counties, in 53 named streams. Ohio designates 174 of those miles as trout water, on 21 streams. The 1 mainstem gauge with a July record read 78.7°F in July.
Open in BirdTrout50°F and colder is cold, through cold-transitional and cool, to warm above 70°F — the same four bands the app paints. On this map the colour is nothing at all: Ohio EPA publishes no thermal classification, so every stream on this map draws grey. The gauge dots are the one exception and they read live. Grey is every stream here, for the reason above.
The watershed in numbers
HUC8 04110004 in the USGS Watershed Boundary Dataset. Every figure below adds up the river pages in this basin — same records, one basin at a time.
Cold, cool and warm water
Ohio publishes no thermal class. What Ohio EPA publishes is an aquatic life use under OAC 3745-1 — Coldwater, Exceptional Warmwater, Warmwater, Modified Warmwater or Limited Resource Habitat — assigned on fish and macroinvertebrate survey scores. It describes the community the water supports, not the temperature it runs at. It covers 0% of this basin's stream miles (0.0 of 1,936); the rest is untyped and is drawn grey on the map above.
Ohio EPA publishes no thermal classification of any stream in the state, so this page has no cold/cool/warm breakdown and none is inferred from the aquatic life use. The coldwater designation is a habitat and management call — OAC 3745-1-07(B)(1)(f) covers both waters holding native coldwater fauna and waters ODNR runs a trout programme on that could be restored to coldwater — and reading a July temperature out of it would be this site inventing one. Ohio water draws grey on the live map; grey means unmeasured.
Every named stream in the basin
All 53 of them, longest first. 14 have a page of their own and are linked; the rest are in the app. The class column is Ohio EPA's designation of that stream. It is not a temperature: this state publishes none, so every row reads untyped in the thermal column. "Now" is the live USGS reading where a gauge stands in that stream.
