9 Ohio EPA aquatic life uses,
2,424 named waters
— Ohio EPA's own data, compiled here so you can search it.

345 of these waters have a full BirdTrout page with live
water temperature, access and public land.
Season dates
Ohio Department of Natural Resources, Division of Wildlife publishes Ohio's trout season dates in the
Ohio Fishing Regulations and does not publish them as data. We do not retype them here,
because a season date typed from memory is the one error on a page like this that costs
the reader a citation — read them at
ODNR Division of Wildlife. What
Ohio EPA does publish as data is the designation each water carries,
and that is the section below.
Limits by species
Ohio's trout and salmon limits are written over the two groups together — “five trout and salmon”, “two trout and salmon combined” — so there is no per-species bag to print. The one species rule Ohio does write singly is the brook trout prohibition on the four eastern rivers, which is in the table above.
Ohio EPA aquatic life uses
Every class Ohio EPA uses, the waters in it, and what the class means. Counts
are of named waters in our copy of the state's data.
Coldwater Habitat
186 named waters · 1,351 mi
Coldwater habitat — OAC 3745-1-07(B)(1)(f). Either water supporting native coldwater fauna year-round, or an inland trout stream the Division of Wildlife runs a trout programme on which has, or could be restored to, coldwater temperature and flow.
Water carrying a rule of its own — a closure, a gear restriction, or a named regulation —
with the water it applies to.
Daily limit · 5 trout and salmon
The statewide limit. “It shall be unlawful for any person to take or possess singly or in the aggregate more than five trout and salmon daily, from any waters in this state.” OAC 1501:31-13-08(E). The four waters below and Lake Erie's drainage are cut to two.
Daily limit · 2 trout and salmon combined
“The Mad river or its tributaries in Clark, Champaign and Logan counties.” OAC 1501:31-13-08(E)(1)(a). Ohio's one substantial wild brown trout river.
Mad River
Daily limit · 2 trout and salmon combined
“The Clear Fork branch of the Mohican river and its tributaries in Ashland and Richland counties.” OAC 1501:31-13-08(E)(1)(b). Note the county list: the length-limit rule below names Richland alone for the same water, and both are carried here as published rather than reconciled.
Clear Fork Mohican River
Daily limit · 2 trout and salmon combined
“Clear creek located in Fairfield and Hocking counties from the first Fairfield county road 69 bridge East of the junction of county road 26 and county road 69 to U.S. route 33 Highway bridge in Hocking county.” OAC 1501:31-13-08(E)(1)(c).
Clear Creek
Daily limit · 2 trout and salmon combined, 1 September – 15 May
“Lake Erie and its tributaries from September first through May fifteenth.” OAC 1501:31-13-08(E)(1)(d). That window is the steelhead run, and it is close to — but not the same as — the October-to-May window Ohio EPA's seasonal salmonid habitat use runs on. Two agencies, two dates, both carried.
Closed · No brook trout
“Take or possess brook trout from the Ashtabula river, Chagrin river, Conneaut river, Grand river, and their tributaries.” OAC 1501:31-13-08(E)(2). Unlawful on the four eastern steelhead rivers and everything that feeds them.
Ashtabula River, Chagrin River, Conneaut Creek, Grand River
Length limit · 12 inches, trout and salmon
“The Mad river or its tributaries in Clark, Champaign and Logan counties” and “the Clear Fork branch of the Mohican river and its tributaries in Richland county.” OAC 1501:31-13-09(B)(1)-(2).
Mad River, Clear Fork Mohican River
Length limit · 12 inches, trout and salmon — the whole Erie basin
“Lake Erie or its direct or indirect tributaries, including all the streams in the entire drainage basin, excepting therefrom Cold creek upstream of state route 2 located in Erie county.” OAC 1501:31-13-09(B)(3). The exception is the one piece of Ohio water that runs cold all summer on its own — the spring at Castalia.
Cold Creek

Nothing has moved since the previous build. This page is rebuilt nightly against
ODNR Division of Wildlife's data and this section fills in the night a season, a limit or a
classification changes.
Coldwater and warmwater rules
Ohio does not regulate trout fishing by classification. The Division of Wildlife's limits attach to four named waters — the Mad, the Clear Fork of the Mohican, Clear creek and Lake Erie's whole drainage — and everywhere else in the state the statewide five-fish limit applies. The class column above is Ohio EPA's aquatic life use under OAC 3745-1, which is a different agency describing what lives in the water rather than what you may keep, and no rule on this page turns on it. Ohio publishes no thermal classification at all, so nothing here should be read as a statement about how cold a stream runs.
Trout fishing near a town in Ohio
The same classification, asked the other way round: what Ohio EPA classifies
as trout water within forty miles of one place, ranked by how much of it is in range.
71 towns in Ohio have one — a town is on this list when
the water near it is not the water near a bigger town down the road.
Verify before you fish. This page is our best-effort compilation from
Ohio Department of Natural Resources, Division of Wildlife data, rebuilt nightly and current as of 2026-09-24. It is not
legal advice and it is not the regulation. Emergency orders, in-season changes and the
stretches an agency describes in words rather than in data will not all be here. Check the
current rules at
